+#          The Exim mail transport agent         #
+##################################################
+# This is the template for Exim's main build-time configuration file. It
+# contains settings that are independent of any operating system. These are
+# things that are mostly sysadmin choices. The items below are divided into
+# those you must specify, those you probably want to specify, those you might
+# often want to specify, and those that you almost never need to mention.
+# Edit this file and save the result to a file called Local/Makefile within the
+# Exim distribution directory before running the "make" command.
+# Things that depend on the operating system have default settings in
+# OS/Makefile-Default, but these are overridden for some OS by files called
+# called OS/Makefile-<osname>. You can further override these by creating files
+# called Local/Makefile-<osname>, where "<osname>" stands for the name of your
+# operating system - look at the names in the OS directory to see which names
+# are recognized.
+# However, if you are building Exim for a single OS only, you don't need to
+# worry about setting up Local/Makefile-<osname>. Any build-time configuration
+# settings you require can in fact be placed in the one file called
+# Local/Makefile. It is only if you are building for several OS from the same
+# source files that you need to worry about splitting off your own OS-dependent
+# settings into separate files. (There's more explanation about how this all
+# works in the toplevel README file, under "Modifying the building process", as
+# well as in the Exim specification.)
+# One OS-specific thing that may need to be changed is the command for running
+# the C compiler; the overall default is gcc, but some OS Makefiles specify cc.
+# You can override anything that is set by putting CC=whatever in your
+# Local/Makefile.
+# NOTE: You should never need to edit any of the distributed Makefiles; all
+# overriding can be done in your Local/Makefile(s). This will make it easier
+# for you when the next release comes along.
+# The location of the X11 libraries is something else that is quite variable
+# even between different versions of the same operating system (and indeed
+# there are different versions of X11 as well, of course). The four settings
+# concerned here are X11, XINCLUDE, XLFLAGS (linking flags) and X11_LD_LIB
+# (dynamic run-time library). You need not worry about X11 unless you want to
+# compile the Exim monitor utility. Exim itself does not use X11.
+# Another area of variability between systems is the type and location of the
+# DBM library package. Exim has support for ndbm, gdbm, tdb, and Berkeley DB.
+# By default the code assumes ndbm; this often works with gdbm or DB, provided
+# they are correctly installed, via their compatibility interfaces. However,
+# Exim can also be configured to use the native calls for Berkeley DB (obsolete
+# versions 1.85, 2.x, 3.x, or the current 4.x version) and also for gdbm.
+# For some operating systems, a default DBM library (other than ndbm) is
+# selected by a setting in the OS-specific Makefile. Most modern OS now have
+# a DBM library installed as standard, and in many cases this will be selected
+# for you by the OS-specific configuration. If Exim compiles without any
+# problems, you probably do not have to worry about the DBM library. If you
+# do want or need to change it, you should first read the discussion in the
+# file doc/dbm.discuss.txt, which also contains instructions for testing Exim's
+# interface to the DBM library.
+# In Local/Makefiles blank lines and lines starting with # are ignored. It is
+# also permitted to use the # character to add a comment to a setting, for
+# example
+#
+# EXIM_GID=42   # the "mail" group
+#
+# However, with some versions of "make" this works only if there is no white
+# space between the end of the setting and the #, so perhaps it is best
+# avoided. A consequence of this facility is that it is not possible to have
+# the # character present in any setting, but I can't think of any cases where
+# this would be wanted.

+###############################################################################
+# Exim will not build unless you specify BIN_DIRECTORY, CONFIGURE_FILE, and
+# EXIM_USER. You also need EXIM_GROUP if EXIM_USER specifies a uid by number.
+# If you don't specify SPOOL_DIRECTORY, Exim won't fail to build. However, it
+# really is a very good idea to specify it here rather than at run time. This
+# is particularly true if you let the logs go to their default location in the
+# spool directory, because it means that the location of the logs is known
+# before Exim has read the run time configuration file.
+#------------------------------------------------------------------------------
+# BIN_DIRECTORY defines where the exim binary will be installed by "make
+# install". The path is also used internally by Exim when it needs to re-invoke
+# itself, either to send an error message, or to recover root privilege. Exim's
+# utility binaries and scripts are also installed in this directory. There is
+# no "standard" place for the binary directory. Some people like to keep all
+# the Exim files under one directory such as /usr/exim; others just let the
+# Exim binaries go into an existing directory such as /usr/sbin or
+# /usr/local/sbin. The installation script will try to create this directory,
+# and any superior directories, if they do not exist.
+#BIN_DIRECTORY=/usr/exim/bin
+BIN_DIRECTORY=/usr/local/exim/etc
+#------------------------------------------------------------------------------
+# CONFIGURE_FILE defines where Exim's run time configuration file is to be
+# found. It is the complete pathname for the file, not just a directory. The
+# location of all other run time files and directories can be changed in the
+# run time configuration file. There is a lot of variety in the choice of
+# location in different OS, and in the preferences of different sysadmins. Some
+# common locations are in /etc or /etc/mail or /usr/local/etc or
+# /usr/local/etc/mail. Another possibility is to keep all the Exim files under
+# a single directory such as /usr/exim. Whatever you choose, the installation
+# script will try to make the directory and any superior directories if they
+# don't exist. It will also install a default runtime configuration if this
+# file does not exist.
+#CONFIGURE_FILE=/usr/exim/configure
+CONFIGURE_FILE=/usr/local/exim/etc/exim.conf
+# It is possible to specify a colon-separated list of files for CONFIGURE_FILE.
+# In this case, Exim will use the first of them that exists when it is run.
+# However, if a list is specified, the installation script no longer tries to
+# make superior directories or to install a default runtime configuration.
+#------------------------------------------------------------------------------
+# The Exim binary must normally be setuid root, so that it starts executing as
+# root, but (depending on the options with which it is called) it does not
+# always need to retain the root privilege. These settings define the user and
+# group that is used for Exim processes when they no longer need to be root. In
+# particular, this applies when receiving messages and when doing remote
+# deliveries. (Local deliveries run as various non-root users, typically as the
+# owner of a local mailbox.) Specifying these values as root is not supported.
+# EXIM_USER=
+# If you specify EXIM_USER as a name, this is looked up at build time, and the
+# uid number is built into the binary. However, you can specify that this
+# lookup is deferred until runtime. In this case, it is the name that is built
+# into the binary. You can do this by a setting of the form:
+EXIM_USER=exim
+# In other words, put "ref:" in front of the user name. If you set EXIM_USER
+# like this, any value specified for EXIM_GROUP is also passed "by reference".
+# Although this costs a bit of resource at runtime, it is convenient to use
+# this feature when building binaries that are to be run on multiple systems
+# where the name may refer to different uids. It also allows you to build Exim
+# on a system where there is no Exim user defined.
+# If the setting of EXIM_USER is numeric (e.g. EXIM_USER=42), there must
+# also be a setting of EXIM_GROUP. If, on the other hand, you use a name
+# for EXIM_USER (e.g. EXIM_USER=exim), you don't need to set EXIM_GROUP unless
+# you want to use a group other than the default group for the given user.
+# EXIM_GROUP=
+# Many sites define a user called "exim", with an appropriate default group,
+# and use
+#
+# EXIM_USER=exim
+#
+# while leaving EXIM_GROUP unspecified (commented out).
+#------------------------------------------------------------------------------
+# SPOOL_DIRECTORY defines the directory where all the data for messages in
+# transit is kept. It is strongly recommended that you define it here, though
+# it is possible to leave this till the run time configuration.
+# Exim creates the spool directory if it does not exist. The owner and group
+# will be those defined by EXIM_USER and EXIM_GROUP, and this also applies to
+# all the files and directories that are created in the spool directory.
+# Almost all installations choose this:
+SPOOL_DIRECTORY=/var/spool/exim

+# embedding the Exim version number into LOOKUP_MODULE_DIR, so that you can
+# maintain two concurrent sets of modules.
+#
+# *BEWARE*: ability to modify the files in LOOKUP_MODULE_DIR is equivalent to
+# the ability to modify the Exim binary, which is often setuid root!  The Exim

+# and we suggest that such packagings' integrity checks should be paranoid
+# about the permissions of the directory and the files within.
+# LOOKUP_MODULE_DIR=/usr/lib/exim/lookups/
+# To build a module dynamically, you'll need to define CFLAGS_DYNAMIC for

+# CFLAGS_DYNAMIC=-shared -rdynamic
+CFLAGS_DYNAMIC=-shared -rdynamic -fPIC
+#------------------------------------------------------------------------------
+# These settings determine which file and database lookup methods are included
+# in the binary. See the manual chapter entitled "File and database lookups"
+# for discussion. DBM and lsearch (linear search) are included by default. If
+# you are unsure about the others, leave them commented out for now.
+# LOOKUP_DNSDB does *not* refer to general mail routing using the DNS. It is
+# for the specialist case of using the DNS as a general database facility (not
+# common).
+# If set to "2" instead of "yes" then the corresponding lookup will be
+# built as a module and must be installed into LOOKUP_MODULE_DIR. You need to
+# add -export-dynamic -rdynamic to EXTRALIBS. You may also need to add -ldl to
+# EXTRALIBS so that dlopen() is available to Exim. You need to define
+# LOOKUP_MODULE_DIR above so the exim binary actually loads dynamic lookup
+# modules.
+# Also, instead of adding all the libraries/includes to LOOKUP_INCLUDE and
+# LOOKUP_LIBS, add them to the respective LOOKUP_*_INCLUDE and LOOKUP_*_LIBS
+# (where * is the name as given here in this list). That ensures that only
+# the dynamic library and not the exim binary will be linked against the
+# library.
+# NOTE: LDAP cannot be built as a module!
+#
+# If your system has pkg-config then the _INCLUDE/_LIBS setting can be

+# LOOKUP_WILDLSEARCH=yes
+# LOOKUP_NWILDLSEARCH=yes
+#------------------------------------------------------------------------------
+# If you have set LOOKUP_LDAP=yes, you should set LDAP_LIB_TYPE to indicate
+# which LDAP library you have. Unfortunately, though most of their functions
+# are the same, there are minor differences. Currently Exim knows about four
+# LDAP libraries: the one from the University of Michigan (also known as

+# The PCRE library is required for exim.  There is no longer an embedded

+# Compiling the Exim monitor: If you want to compile the Exim monitor, a

+# Compiling Exim with content scanning support: If you want to compile Exim

+WITH_CONTENT_SCAN=yes
+# If you want to use the deprecated "demime" condition in the DATA ACL,

+# the "demime" condition.
+# WITH_OLD_DEMIME=yes
+# If you're using ClamAV and are backporting fixes to an old version, instead
+# of staying current (which is the more usual approach) then you may need to
+# use an older API which uses a STREAM command, now deprecated, instead of
+# zINSTREAM.  If you need to set this, please let the Exim developers know, as

+# The items in this section are those that are commonly changed according to
+# the sysadmin's preferences, but whose defaults are often acceptable. The
+# first five are concerned with security issues, where differing levels of
+# paranoia are appropriate in different environments. Sysadmins also vary in
+# their views on appropriate levels of defence in these areas. If you do not
+# understand these issues, go with the defaults, which are used by many sites.
+#------------------------------------------------------------------------------
+# Although Exim is normally a setuid program, owned by root, it refuses to run
+# local deliveries as root by default. There is a runtime option called
+# "never_users" which lists the users that must never be used for local
+# deliveries. There is also the setting below, which provides a list that
+# cannot be overridden at runtime. This guards against problems caused by
+# unauthorized changes to the runtime configuration. You are advised not to
+# remove "root" from this option, but you can add other users if you want. The
+# list is colon-separated. It must NOT contain any spaces.
+# FIXED_NEVER_USERS=root:bin:daemon
+FIXED_NEVER_USERS=root
+#------------------------------------------------------------------------------
+# By default, Exim insists that its configuration file be owned by root. You
+# can specify one additional permitted owner here.
+CONFIGURE_OWNER=exim-test
+# If the configuration file is group-writeable, Exim insists by default that it
+# is owned by root. You can specify one additional permitted group owner here.
+CONFIGURE_GROUP=exim-test
+# If you specify CONFIGURE_OWNER or CONFIGURE_GROUP as a name, this is looked
+# up at build time, and the uid or gid number is built into the binary.
+# However, you can specify that the lookup is deferred until runtime. In this
+# case, it is the name that is built into the binary. You can do this by a
+# setting of the form:
+# CONFIGURE_OWNER=ref:mail
+# CONFIGURE_GROUP=ref:sysadmin
+# In other words, put "ref:" in front of the user or group name. Although this
+# costs a bit of resource at runtime, it is convenient to use this feature when
+# building binaries that are to be run on multiple systems where the names may
+# refer to different uids or gids. It also allows you to build Exim on a system
+# where the relevant user or group is not defined.
+#------------------------------------------------------------------------------
+# The -C option allows Exim to be run with an alternate runtime configuration
+# file. When this is used by root, root privilege is retained by the binary
+# (for any other caller including the Exim user, it is dropped). You can
+# restrict the location of alternate configurations by defining a prefix below.
+# Any file used with -C must then start with this prefix (except that /dev/null
+# is also permitted if the caller is root, because that is used in the install
+# script). If the prefix specifies a directory that is owned by root, a
+# compromise of the Exim account does not permit arbitrary alternate
+# configurations to be used. The prefix can be more restrictive than just a
+# directory (the second example).
+# ALT_CONFIG_PREFIX=/some/directory/
+# ALT_CONFIG_PREFIX=/some/directory/exim.conf-
+#------------------------------------------------------------------------------
+# When a user other than root uses the -C option to override the configuration
+# file (including the Exim user when re-executing Exim to regain root
+# privileges for local message delivery), this will normally cause Exim to
+# drop root privileges. The TRUSTED_CONFIG_LIST option, specifies a file which
+# contains a list of trusted configuration filenames, one per line. If the -C
+# option is used by the Exim user or by the user specified in the
+# CONFIGURE_OWNER setting, to specify a configuration file which is listed in
+# the TRUSTED_CONFIG_LIST file, then root privileges are not dropped by Exim.
+TRUSTED_CONFIG_LIST=/tmp/exim/trusted-configs
+#------------------------------------------------------------------------------
+# Uncommenting this option disables the use of the -D command line option,
+# which changes the values of macros in the runtime configuration file.
+# This is another protection against somebody breaking into the Exim account.
+# DISABLE_D_OPTION=yes
+#------------------------------------------------------------------------------
+# By contrast, you might be maintaining a system which relies upon the ability
+# to override values with -D and assumes that these will be passed through to
+# the delivery processes.  As of Exim 4.73, this is no longer the case by
+# default.  Going forward, we strongly recommend that you use a shim Exim
+# configuration file owned by root stored under TRUSTED_CONFIG_LIST.
+# That shim can set macros before .include'ing your main configuration file.
+#
+# As a strictly transient measure to ease migration to 4.73, the
+# WHITELIST_D_MACROS value definies a colon-separated list of macro-names
+# which are permitted to be overridden from the command-line which will be
+# honoured by the Exim user.  So these are macros that can persist to delivery
+# time.
+# Examples might be -DTLS or -DSPOOL=/some/dir.  The values on the
+# command-line are filtered to only permit: [A-Za-z0-9_/.-]*
+#
+# This option is highly likely to be removed in a future release.  It exists
+# only to make 4.73 as easy as possible to migrate to.  If you use it, we
+# encourage you to schedule time to rework your configuration to not depend
+# upon it.  Most people should not need to use this.

+# Exim has support for the AUTH (authentication) extension of the SMTP
+# protocol, as defined by RFC 2554. If you don't know what SMTP authentication
+# is, you probably won't want to include this code, so you should leave these
+# settings commented out. If you do want to make use of SMTP authentication,
+# you must uncomment at least one of the following, so that appropriate code is
+# included in the Exim binary. You will then need to set up the run time
+# configuration to make use of the mechanism(s) selected.
+AUTH_CRAM_MD5=yes
+# AUTH_CYRUS_SASL=yes
+AUTH_DOVECOT=yes
+# AUTH_GSASL=yes
+# AUTH_GSASL_PC=libgsasl
+# AUTH_HEIMDAL_GSSAPI=yes
+# AUTH_HEIMDAL_GSSAPI_PC=heimdal-gssapi
+AUTH_PLAINTEXT=yes
+AUTH_SPA=yes
+#------------------------------------------------------------------------------
+# If you specified AUTH_CYRUS_SASL above, you should ensure that you have the
+# Cyrus SASL library installed before trying to build Exim, and you probably
+# want to uncomment the first line below.
+# Similarly for GNU SASL, unless pkg-config is used via AUTH_GSASL_PC.
+# Ditto for AUTH_HEIMDAL_GSSAPI(_PC).
+# AUTH_LIBS=-lsasl2
+# AUTH_LIBS=-lgsasl
+# AUTH_LIBS=-lgssapi -lheimntlm -lkrb5 -lhx509 -lcom_err -lhcrypto -lasn1 -lwind -lroken -lcrypt
+#------------------------------------------------------------------------------
+# When Exim is decoding MIME "words" in header lines, most commonly for use
+# in the $header_xxx expansion, it converts any foreign character sets to the
+# one that is set in the headers_charset option. The default setting is
+# defined by this setting:
+HEADERS_CHARSET="ISO-8859-1"
+# If you are going to make use of $header_xxx expansions in your configuration
+# file, or if your users are going to use them in filter files, and the normal
+# character set on your host is something other than ISO-8859-1, you might
+# like to specify a different default here. This value can be overridden in
+# the runtime configuration, and it can also be overridden in individual filter
+# files.
+#
+# IMPORTANT NOTE: The iconv() function is needed for character code
+# conversions. Please see the next item...
+#------------------------------------------------------------------------------
+# Character code conversions are possible only if the iconv() function is
+# installed on your operating system. There are two places in Exim where this
+# is relevant: (a) The $header_xxx expansion (see the previous item), and (b)
+# the Sieve filter support. For those OS where iconv() is known to be installed
+# as standard, the file in OS/Makefile-xxxx contains
+#
+# HAVE_ICONV=yes
+#
+# If you are not using one of those systems, but have installed iconv(), you
+# need to uncomment that line above. In some cases, you may find that iconv()
+# and its header file are not in the default places. You might need to use
+# something like this:
+#
+# HAVE_ICONV=yes
+# CFLAGS=-O -I/usr/local/include
+# EXTRALIBS_EXIM=-L/usr/local/lib -liconv
+#
+# but of course there may need to be other things in CFLAGS and EXTRALIBS_EXIM
+# as well.
+#------------------------------------------------------------------------------
+# The passwords for user accounts are normally encrypted with the crypt()
+# function. Comparisons with encrypted passwords can be done using Exim's
+# "crypteq" expansion operator. (This is commonly used as part of the
+# configuration of an authenticator for use with SMTP AUTH.) At least one
+# operating system has an extended function called crypt16(), which uses up to
+# 16 characters of a password (the normal crypt() uses only the first 8). Exim
+# supports the use of crypt16() as well as crypt() but note the warning below.
+# You can always indicate a crypt16-encrypted password by preceding it with
+# "{crypt16}". If you want the default handling (without any preceding
+# indicator) to use crypt16(), uncomment the following line:
+# DEFAULT_CRYPT=crypt16
+# If you do that, you can still access the basic crypt() function by preceding
+# an encrypted password with "{crypt}". For more details, see the description
+# of the "crypteq" condition in the manual chapter on string expansions.
+# Some operating systems do not include a crypt16() function, so Exim has one
+# of its own, which it uses unless HAVE_CRYPT16 is defined. Normally, that will
+# be set in an OS-specific Makefile for the OS that have such a function, so
+# you should not need to bother with it.
+# *** WARNING *** WARNING *** WARNING *** WARNING *** WARNING ***
+# It turns out that the above is not entirely accurate. As well as crypt16()
+# there is a function called bigcrypt() that some operating systems have. This
+# may or may not use the same algorithm, and both of them may be different to
+# Exim's built-in crypt16() that is used unless HAVE_CRYPT16 is defined.
+#
+# However, since there is now a move away from the traditional crypt()
+# functions towards using SHA1 and other algorithms, tidying up this area of
+# Exim is seen as very low priority. In practice, if you need to, you can
+# define DEFAULT_CRYPT to the name of any function that has the same interface
+# as the traditional crypt() function.
+# *** WARNING *** WARNING *** WARNING *** WARNING *** WARNING ***
+#------------------------------------------------------------------------------
+# Exim can be built to support the SMTP STARTTLS command, which implements
+# Transport Layer Security using SSL (Secure Sockets Layer). To do this, you
+# must install the OpenSSL library package or the GnuTLS library. Exim contains
+# no cryptographic code of its own. Uncomment the following lines if you want
+# to build Exim with TLS support. If you don't know what this is all about,
+# leave these settings commented out.
+# This setting is required for any TLS support (either OpenSSL or GnuTLS)
+SUPPORT_TLS=yes
+# Uncomment one of these settings if you are using OpenSSL; pkg-config vs not
+USE_OPENSSL_PC=openssl
+#TLS_LIBS=-lssl -lcrypto
+# Uncomment the first and either the second or the third of these if you
+# are using GnuTLS.  If you have pkg-config, then the second, else the third.
+#USE_GNUTLS=yes
+# USE_GNUTLS_PC=gnutls
+#TLS_LIBS=-lgnutls -ltasn1 -lgcrypt
+# If you are running Exim as a server, note that just building it with TLS
+# support is not all you need to do. You also need to set up a suitable
+# certificate, and tell Exim about it by means of the tls_certificate
+# and tls_privatekey run time options. You also need to set tls_advertise_hosts
+# to specify the hosts to which Exim advertises TLS support. On the other hand,
+# if you are running Exim only as a client, building it with TLS support
+# is all you need to do.
+# If you are using pkg-config then you should not need to worry where the
+# libraries and headers are installed, as the pkg-config .pc specification
+# should include all -L/-I information necessary.  If not using pkg-config
+# then you might need to specify the locations too.
+# Additional libraries and include files are required for both OpenSSL and
+# GnuTLS. The TLS_LIBS settings above assume that the libraries are installed
+# with all your other libraries. If they are in a special directory, you may
+# need something like
+# TLS_LIBS=-L/usr/local/openssl/lib -lssl -lcrypto
+# or
+# TLS_LIBS=-L/opt/gnu/lib -lgnutls -ltasn1 -lgcrypt
+# TLS_LIBS is included only on the command for linking Exim itself, not on any
+# auxiliary programs. If the include files are not in a standard place, you can
+# set TLS_INCLUDE to specify where they are, for example:
+# TLS_INCLUDE=-I/usr/local/openssl/include/
+# or
+# TLS_INCLUDE=-I/opt/gnu/include
+# You don't need to set TLS_INCLUDE if the relevant directories are already
+# specified in INCLUDE.
+#------------------------------------------------------------------------------
+# The default distribution of Exim contains only the plain text form of the
+# documentation. Other forms are available separately. If you want to install
+# the documentation in "info" format, first fetch the Texinfo documentation
+# sources from the ftp directory and unpack them, which should create files
+# with the extension "texinfo" in the doc directory. You may find that the
+# version number of the texinfo files is different to your Exim version number,
+# because the main documentation isn't updated as often as the code. For
+# example, if you have Exim version 4.43, the source tarball upacks into a
+# directory called exim-4.43, but the texinfo tarball unpacks into exim-4.40.
+# In this case, move the contents of exim-4.40/doc into exim-4.43/doc after you
+# have unpacked them. Then set INFO_DIRECTORY to the location of your info
+# directory. This varies from system to system, but is often /usr/share/info.
+# Once you have done this, "make install" will build the info files and
+# install them in the directory you have defined.
+# INFO_DIRECTORY=/usr/share/info
+#------------------------------------------------------------------------------
+# Exim log directory and files: Exim creates several log files inside a
+# single log directory. You can define the directory and the form of the
+# log file name here. If you do not set anything, Exim creates a directory
+# called "log" inside its spool directory (see SPOOL_DIRECTORY above) and uses
+# the filenames "mainlog", "paniclog", and "rejectlog". If you want to change
+# this, you can set LOG_FILE_PATH to a path name containing one occurrence of
+# %s. This will be replaced by one of the strings "main", "panic", or "reject"
+# to form the final file names. Some installations may want something like this:
+# LOG_FILE_PATH=/var/log/exim_%slog
+# which results in files with names /var/log/exim_mainlog, etc. The directory
+# in which the log files are placed must exist; Exim does not try to create
+# it for itself. It is also your responsibility to ensure that Exim is capable
+# of writing files using this path name. The Exim user (see EXIM_USER above)
+# must be able to create and update files in the directory you have specified.
+# You can also configure Exim to use syslog, instead of or as well as log
+# files, by settings such as these
+# LOG_FILE_PATH=syslog
+# LOG_FILE_PATH=syslog:/var/log/exim_%slog
+# The first of these uses only syslog; the second uses syslog and also writes
+# to log files. Do not include white space in such a setting as it messes up
+# the building process.
+#------------------------------------------------------------------------------
+# When logging to syslog, the following option caters for syslog replacements
+# that are able to accept log entries longer than the 1024 characters allowed
+# by RFC 3164. It is up to you to make sure your syslog daemon can handle this.
+# Non-printable characters are usually unacceptable regardless, so log entries
+# are still split on newline characters.
+# SYSLOG_LONG_LINES=yes
+# If you are not interested in the process identifier (pid) of the Exim that is
+# making the call to syslog, then comment out the following line.
+SYSLOG_LOG_PID=yes
+#------------------------------------------------------------------------------
+# Cycling log files: this variable specifies the maximum number of old
+# log files that are kept by the exicyclog log-cycling script. You don't have
+# to use exicyclog. If your operating system has other ways of cycling log
+# files, you can use them instead. The exicyclog script isn't run by default;
+# you have to set up a cron job for it if you want it.
+EXICYCLOG_MAX=10
+#------------------------------------------------------------------------------
+# The compress command is used by the exicyclog script to compress old log
+# files. Both the name of the command and the suffix that it adds to files
+# need to be defined here. See also the EXICYCLOG_MAX configuration.
+COMPRESS_COMMAND=/usr/bin/gzip
+COMPRESS_SUFFIX=gz
+#------------------------------------------------------------------------------
+# If the exigrep utility is fed compressed log files, it tries to uncompress
+# them using this command.
+ZCAT_COMMAND=/usr/bin/zcat
+#------------------------------------------------------------------------------
+# Compiling in support for embedded Perl: If you want to be able to
+# use Perl code in Exim's string manipulation language and you have Perl
+# (version 5.004 or later) installed, set EXIM_PERL to perl.o. Using embedded
+# Perl costs quite a lot of resources. Only do this if you really need it.
+EXIM_PERL=perl.o
+#------------------------------------------------------------------------------
+# Support for dynamically-loaded string expansion functions via ${dlfunc. If
+# you are using gcc the dynamically-loaded object must be compiled with the
+# -shared option, and you will need to add -export-dynamic to EXTRALIBS so
+# that the local_scan API is made available by the linker. You may also need
+# to add -ldl to EXTRALIBS so that dlopen() is available to Exim.
+EXPAND_DLFUNC=yes
+#jgh
+EXTRALIBS= -export-dynamic
+#------------------------------------------------------------------------------
+# Exim has support for PAM (Pluggable Authentication Modules), a facility
+# which is available in the latest releases of Solaris and in some GNU/Linux
+# distributions (see http://ftp.kernel.org/pub/linux/libs/pam/). The Exim
+# support, which is intended for use in conjunction with the SMTP AUTH
+# facilities, is included only when requested by the following setting:
+# SUPPORT_PAM=yes
+# You probably need to add -lpam to EXTRALIBS, and in some releases of
+# GNU/Linux -ldl is also needed.
+#------------------------------------------------------------------------------
+# Support for authentication via Radius is also available. The Exim support,
+# which is intended for use in conjunction with the SMTP AUTH facilities,
+# is included only when requested by setting the following parameter to the
+# location of your Radius configuration file:
+# RADIUS_CONFIG_FILE=/etc/radiusclient/radiusclient.conf
+# RADIUS_CONFIG_FILE=/etc/radius.conf
+# If you have set RADIUS_CONFIG_FILE, you should also set one of these to
+# indicate which RADIUS library is used:
+# RADIUS_LIB_TYPE=RADIUSCLIENT
+# RADIUS_LIB_TYPE=RADIUSCLIENTNEW
+# RADIUS_LIB_TYPE=RADLIB
+# RADIUSCLIENT is the radiusclient library; you probably need to add
+#   -lradiusclient to EXTRALIBS.
+#
+# The API for the radiusclient library was changed at release 0.4.0.
+# Unfortunately, the header file does not define a version number that clients
+# can use to support both the old and new APIs. If you are using version 0.4.0
+# or later of the radiusclient library, you should use RADIUSCLIENTNEW.
+#
+# RADLIB is the Radius library that comes with FreeBSD (the header file is
+#   called radlib.h); you probably need to add -lradius to EXTRALIBS.
+#
+# If you do not set RADIUS_LIB_TYPE, Exim assumes the radiusclient library,
+# using the original API.
+#------------------------------------------------------------------------------
+# Support for authentication via the Cyrus SASL pwcheck daemon is available.
+# Note, however, that pwcheck is now deprecated in favour of saslauthd (see
+# next item). The Exim support for pwcheck, which is intented for use in
+# conjunction with the SMTP AUTH facilities, is included only when requested by
+# setting the following parameter to the location of the pwcheck daemon's
+# socket.
+#
+# There is no need to install all of SASL on your system. You just need to run
+# ./configure --with-pwcheck, cd to the pwcheck directory within the sources,
+# make and make install. You must create the socket directory (default
+# /var/pwcheck) and chown it to exim's user and group. Once you have installed
+# pwcheck, you should arrange for it to be started by root at boot time.
+# CYRUS_PWCHECK_SOCKET=/var/pwcheck/pwcheck
+#------------------------------------------------------------------------------
+# Support for authentication via the Cyrus SASL saslauthd daemon is available.
+# The Exim support, which is intented for use in conjunction with the SMTP AUTH
+# facilities, is included only when requested by setting the following
+# parameter to the location of the saslauthd daemon's socket.
+#
+# There is no need to install all of SASL on your system. You just need to run
+# ./configure --with-saslauthd (and any other options you need, for example, to
+# select or deselect authentication mechanisms), cd to the saslauthd directory
+# within the sources, make and make install. You must create the socket

+# TCP wrappers: If you want to use tcpwrappers from within Exim, uncomment
+# this setting. See the manual section entitled "Use of tcpwrappers" in the
+# chapter on building and installing Exim.
+#
+# USE_TCP_WRAPPERS=yes
+#
+# You may well also have to specify a local "include" file and an additional
+# library for TCP wrappers, so you probably need something like this:
+#
+# USE_TCP_WRAPPERS=yes
+# CFLAGS=-O -I/usr/local/include
+# EXTRALIBS_EXIM=-L/usr/local/lib -lwrap
+#
+# but of course there may need to be other things in CFLAGS and EXTRALIBS_EXIM
+# as well.
+#
+# To use a name other than exim in the tcpwrappers config file,
+# e.g. if you're running multiple daemons with different access lists,
+# or multiple MTAs with the same access list, define
+# TCP_WRAPPERS_DAEMON_NAME accordingly
+#
+# TCP_WRAPPERS_DAEMON_NAME="exim"
+#------------------------------------------------------------------------------
+# The default action of the exim_install script (which is run by "make
+# install") is to install the Exim binary with a unique name such as
+# exim-4.43-1, and then set up a symbolic link called "exim" to reference it,
+# moving the symbolic link from any previous version. If you define NO_SYMLINK
+# (the value doesn't matter), the symbolic link is not created or moved. You
+# will then have to "turn Exim on" by setting up the link manually.
+# NO_SYMLINK=yes
+#------------------------------------------------------------------------------
+# Another default action of the install script is to install a default runtime
+# configuration file if one does not exist. This configuration has a router for
+# expanding system aliases. The default assumes that these aliases are kept
+# in the traditional file called /etc/aliases. If such a file does not exist,
+# the installation script creates one that contains just comments (no actual
+# aliases). The following setting can be changed to specify a different
+# location for the system alias file.
+SYSTEM_ALIASES_FILE=/etc/aliases
+#------------------------------------------------------------------------------
+# There are some testing options (-be, -bt, -bv) that read data from the
+# standard input when no arguments are supplied. By default, the input lines
+# are read using the standard fgets() function. This does not support line
+# editing during interactive input (though the terminal's "erase" character
+# works as normal). If your operating system has the readline() function, and
+# in addition supports dynamic loading of library functions, you can cause
+# Exim to use readline() for the -be testing option (only) by uncommenting the
+# following setting. Dynamic loading is used so that the library is loaded only
+# when the -be testing option is given; by the time the loading occurs,
+# Exim has given up its root privilege and is running as the calling user. This
+# is the reason why readline() is NOT supported for -bt and -bv, because Exim
+# runs as root or as exim, respectively, for those options. When USE_READLINE
+# is "yes", as well as supporting line editing, a history of input lines in the
+# current run is maintained.
+# USE_READLINE=yes
+# You may need to add -ldl to EXTRALIBS when you set USE_READLINE=yes.
+# Note that this option adds to the size of the Exim binary, because the
+# dynamic loading library is not otherwise included.

+# Only in rare circumstances should you need to change this.
+# AR=ar cq
+#------------------------------------------------------------------------------
+# In some operating systems, the value of the TMPDIR environment variable
+# controls where temporary files are created. Exim does not make use of
+# temporary files, except when delivering to MBX mailboxes. However, if Exim
+# calls any external libraries (e.g. DBM libraries), they may use temporary
+# files, and thus be influenced by the value of TMPDIR. For this reason, when
+# Exim starts, it checks the environment for TMPDIR, and if it finds it is set,
+# it replaces the value with what is defined here. Commenting this setting
+# suppresses the check altogether.
+TMPDIR="/tmp"
+#------------------------------------------------------------------------------
+# The following macros can be used to change the default modes that are used

+#------------------------------------------------------------------------------
+# In some installations there may be multiple machines sharing file systems,
+# where a different configuration file is required for Exim on the different
+# machines. If CONFIGURE_FILE_USE_NODE is defined, then Exim will first look
+# for a configuration file whose name is that defined by CONFIGURE_FILE,
+# with the node name obtained by uname() tacked on the end, separated by a
+# period (for example, /usr/exim/configure.host.in.some.domain). If this file
+# does not exist, then the bare configuration file name is tried.
+# CONFIGURE_FILE_USE_NODE=yes
+#------------------------------------------------------------------------------
+# In some esoteric configurations two different versions of Exim are run,
+# with different setuid values, and different configuration files are required
+# to handle the different cases. If CONFIGURE_FILE_USE_EUID is defined, then
+# Exim will first look for a configuration file whose name is that defined
+# by CONFIGURE_FILE, with the effective uid tacked on the end, separated by
+# a period (for eximple, /usr/exim/configure.0). If this file does not exist,
+# then the bare configuration file name is tried. In the case when both
+# CONFIGURE_FILE_USE_EUID and CONFIGURE_FILE_USE_NODE are set, four files
+# are tried: <name>.<euid>.<node>, <name>.<node>, <name>.<euid>, and <name>.
+# CONFIGURE_FILE_USE_EUID=yes
+#------------------------------------------------------------------------------
+# The size of the delivery buffers: These specify the sizes (in bytes) of

+# DELIVER_OUT_BUFFER_SIZE=8192
+#------------------------------------------------------------------------------
+# The mode of the database directory: Exim creates a directory called "db"

+#------------------------------------------------------------------------------
+# This parameter sets the maximum length of the header portion of a message

+# the call to the OS that does this requires a buffer large enough to hold
+# data for all the interfaces - it was designed in the days when a host rarely
+# had more than three or four interfaces. Nowadays hosts can have very many
+# virtual interfaces running on the same hardware. If you have more than 250
+# virtual interfaces, you will need to uncomment this setting and increase the

+# Per-message logs: While a message is in the process of being delivered,
+# comments on its progress are written to a message log, for the benefit of
+# human administrators. These logs are held in a directory called "msglog"
+# in the spool directory. Its mode defaults to 0750, but can be changed here.
+# The message log directory is also used for storing files that are used by
+# transports for returning data to a message's sender (see the "return_output"
+# option for transports).
+# MSGLOG_DIRECTORY_MODE=0750
+#------------------------------------------------------------------------------
+# There are three options which are used when compiling the Perl interface and
+# when linking with Perl. The default values for these are placed automatically
+# at the head of the Makefile by the script which builds it. However, if you
+# want to override them, you can do so here.

+# Identifying the daemon: When an Exim daemon starts up, it writes its pid
+# (process id) to a file so that it can easily be identified. The path of the
+# file can be specified here. Some installations may want something like this:
+# PID_FILE_PATH=/var/lock/exim.pid
+# If PID_FILE_PATH is not defined, Exim writes a file in its spool directory
+# using the name "exim-daemon.pid".
+# If you start up a daemon without the -bd option (for example, with just
+# the -q15m option), a pid file is not written. Also, if you override the
+# configuration file with the -oX option, no pid file is written. In other
+# words, the pid file is written only for a "standard" daemon.
+#------------------------------------------------------------------------------
+# If Exim creates the spool directory, it is given this mode, defaulting in the
+# source to 0750.
+# SPOOL_DIRECTORY_MODE=0750
+#------------------------------------------------------------------------------
+# The mode of files on the input spool which hold the contents of messages can
+# be changed here. The default is 0640 so that information from the spool is
+# available to anyone who is a member of the Exim group.
+# SPOOL_MODE=0640
+#------------------------------------------------------------------------------
+# Moving frozen messages: If the following is uncommented, Exim is compiled
+# with support for automatically moving frozen messages out of the main spool
+# directory, a facility that is found useful by some large installations. A
+# run time option is required to cause the moving actually to occur. Such
+# messages become "invisible" to the normal management tools.
+# SUPPORT_MOVE_FROZEN_MESSAGES=yes
+#------------------------------------------------------------------------------
+# Expanding match_* second paramters: BE CAREFUL IF ENABLING THIS!
+# It has proven too easy in practice for administrators to configure security
+# problems into their Exim install, by treating match_domain{}{} and friends
+# as a form of string comparison, where the second string comes from untrusted
+# data. Because these options take lists, which can include lookup;LOOKUPDATA
+# style elements, a foe can then cause Exim to, eg, execute an arbitrary MySQL
+# query, dropping tables.
+# From Exim 4.77 onwards, the second parameter is not expanded; it can still
+# be a list literal, or a macro, or a named list reference.  There is also
+# the new expansion condition "inlisti" which does expand the second parameter,
+# but treats it as a list of strings; also, there's "eqi" which is probably
+# what is normally wanted.
+#
+# If you really need to have the old behaviour, know what you are doing and
+# will not complain if your system is compromised as a result of doing so, then
+# uncomment this option to get the old behaviour back.
+# EXPAND_LISTMATCH_RHS=yes
+#------------------------------------------------------------------------------
+# Disabling the use of fsync(): DO NOT UNCOMMENT THE FOLLOWING LINE unless you
+# really, really, really know what you are doing. And even then, think again.
+# You should never uncomment this when compiling a binary for distribution.
+# Use it only when compiling Exim for your own use.
+#
+# Uncommenting this line enables the use of a runtime option called
+# disable_fsync, which can be used to stop Exim using fsync() to ensure that
+# files are written to disc before proceeding. When this is disabled, crashes
+# and hardware problems such as power outages can cause data to be lost. This
+# feature should only be used in very exceptional circumstances. YOU HAVE BEEN
+# WARNED.
+# ENABLE_DISABLE_FSYNC=yes
