-        - Start Daemon

-        - lists, lookups, … "dynamisch"
-    - Config-Parser: nur simple Syntax-Checks
-    - trim, "de-comment"

-
-### strings
-    Fromat: <string>           eg: localhost
-            <"string">         eg: " A\x42C"
-
-    Quoting für \\, \n, \r, \t, \ddd, \xdd und führende oder baumelnde Spaces
-
-    - Vorsicht: Expansion
-    - Vorsicht: User/Groups
-
-    +----------------+---------+------------+------------------+
-    |primary_hostname|Use: main|Type: string|Default: see below|
-    +----------------+---------+------------+------------------+

-    > exim -C <(echo 'primary_hostname = "a\x41b"') -bP primary_hostname
-
-    Steuerzeichen werden für die Ausgabe escaped:
-    > exim -C <(echo 'primary_hostname = "a\x091b"') -bP primary_hostname
-
-
-### Lists
-    Format: <item>:…            eg:   a:b:c:d vs. a:b::c:d
-                                eg:   :   -> ein leeres Element
-        [<<sep> <item><sep>…]   eg:   <, a,b,c
-
-      - leere Felder am Ende werden „gestrippt“
-      - Whitespace der Felder wird gestrippt
-      - leeres Feld in der Mitte: a: :b
-      - leeres Felder am Anfang bleibt
-      - "Escapen" des Listentrenners durch Verdoppeln
-
-      a : b::c : d -> (a) (b:c) (d)
-
-    > exim -be '${map{:a:b:c,}{<$item>}}'
-    > exim -be '${map{<,,a,b,c,}{<$item>}}'
-
-    > exim -C <(echo domainlist local_domains = 'a:b::c:d') -be '${listnamed:local_domains}'
-
-
-### Regexp
-    Format ^…
-
-    Beginnt mit ^, damit es sich von einem normalen String unterscheidet!
-    Achtung, Backslash ggf. vom String-Expander gefressen,
-    hauptsächlich in Listen, die RE enthalten dürfen
-
-    Ggf. mit \N..\N 
-
-## Lookups
-
-    - 2 Syntaxen
-    - 2 Types
-    => 4 Varianten
-
-### Syntax 1: explizit - der Key oder die Frage wird ausdrücklich formuliert
-              es ist ein String-Expansion. s.u.
-
-    ${lookup{<key>}<type>{file}}    eg: ${lookup{$domain}dsearch{/etc/exim4/domains}}
-    ${lookup <type> {<query>}}      eg: ${lookup ldap {ldap:///o=roka?mail?sub?uid=${quote_ldap:$local_part}}}
-
-    Liefert eine Liste zurück, ggf. Listentrenner unorthodox und muss massiert werden
-
-### Syntax 2: implizit - der Key ergibt sich aus dem Kontext
-              keine Stringexpansion, sondern ein Element für sich
-
-
-    <type>;<file>                   eg: domains = dsearch;/etc/exim4/domains
-    <type>;<query>                  eg: domains = sqlite;/etc/db.sqlite SELECT … WHERE ${quote_sqlite:$local_part} …
-                                        domains = ldap;ldap:///o=roka?mail?sub?…
-
-    - Auffindes des "impliziten" Keys
-    - Query: Success der Query ist entscheidend, nicht der Resultat-Wert
-    - Achtung: In einer Liste ggf. an den Listentrenner denken!
-               domains = ldap;ldap::///o=…
-
-### Style 1: Single Key
-
-    ${lookup{<key>}<type>{<file>}   eg: ${lookup{$sender_host_address}iplsearch{/etc/exim4/blacklist}}
-    <type>;<file>                   eg: hosts = iplsearch;/etc/exim4/blacklist
-
-    <type> ist dann lsearch, dsearch, iplsearch, …
-    
-### Style 2: Query Style
-
-    ${lookup <type> {<query>}}      eg: ${lookup dnsdb{mxh=roka.net}}
-    <type>;<query>                  eg: dnsdb;mxh=roka.net
-
-
-    Matrix
-
-        style|  single key                    | query style
-    syntax  \|                                |
-    ---------+--------------------------------+---------------------------
-    explicit |  ${lookup{<key>}<type>{<file>} | ${lookup <type> {<query>}}
-    implizit |  <type>;<file>                 | [ <type>;<query> ]
-
-
-    eg. config:
-
-    domains = ${lookup{$domain}lsearch{/etc/exim4/local_domains}}   # WRONG
-            = <\n ${lookup mysql { SELECT domain FROM domains }}    # BETTER
-            = ${lookup mysql { SELECT DISTINCT(domain) FROM domains WHERE domain = $domain}} # ggf BEST
-    vs
-    domains = lsearch;/etc/exim4/local_domains                      # OK
-
-
-## Named Lists
-   Format: <listtype> <name>
-           <listtype>_cache <name>
-           Bezug: +<name>
-
-    Typen: domainlist, hostlist, addresslist, localpartlist
-    Caching nur wenn die RHS keine '$' enthält, also konstante Ergebnisse zu erwarten sind.
-
-    Jeder Listtyp hat seine Eigenarten.
-
-    > exim -bP +<name>
-
-### domainlist
-
-    domainlist - @, @mx_primary, @mx_secondary, @mx_any, <pattern>, lookup, literal
-    hostlist   - Namen, Adressen spec(10.11 ff)
-
-
-## String-Expansion
-
-    - von links nach rechts: $ und \ wirken als Trigger
-
-    > exim -be [<string>]
-    > exim -bem <message-file> [<string>]
-    > exim -be -Mset <spool-id> [<string>]
-
-    eg: exim -be '$primary_hostname'
-        exim -be '$tod_full'
-        exim -bem <(echo 'Subject: Hi') '$h_subject:'
-
-    Expansionen liefern neuen Text zurück oder können „forced expansion failure“
-    bewirken
-
-## Expansions-Items
-
-### Variablen
-    Format: $<variable>           eg: $localhost_number
-            ${<variable>}     
-
-### Operatoren
-    Format: ${<op>:<string>}
-    Für einfache Expansionen, lc, uc, hash, …
-
-### Funktionen
-    Format ${<function>{string1}...}

-    eg: acl_smtp_rcpt = acl_check_rcpt
-        acl_smtp_rcpt = acl_check_rcpt_${primary_hostname}
-
-## Policies
-
-### acl_smtp_rcpt
- 
-    Abweisung einzelner Empfänger, noch kein Content!
-
-### acl_smtp_data
-
-    Content-Scan. Nicht mehr für einzelne Empfänger,
-    $local_part, $domain steht nicht mehr zur Verfügung,
-    aber $recpients, $rcpt_count, …
-
-## Return-Values
-
-    - accept
-    - defer
-    - deny
-    - discard
-
-    default: "accept", ausser bei acl_smtp_rcpt, dort ist es "deny"
-    implizit "deny" am Ende jeder ACL!
-
-
-## Test
-
-   > exim -bh <ip>  # ohne callouts
-   > exim -bhc <ip> # mit callouts
-   > swaks --pipe 'exim -bh <ip> -C <config>' -f <sender> -t <rcpt>
-
-   exim -N hilft nicht, ist nicht für die SMTP acl
-   relevant!
-
-## Format
-
-   <aclverb>    [<condition>]
-                …
-                [<modifier]
-
-   Bedingungen müssen erfüllt sein, Order matters, Abbruch
-   bei nicht erfüllter Bedingung! Modifier sind immer "true"
-
-### Verb
-
-   accept, defer, deny, discard, drop, require, warn
-
-### Modifier
-
-    message = [code] text
-    log_message = text
-
-    Immediate:
-        logwrite      = …
-        control       = …
-        set           = …
-        add_header    = …
-        remove_header = …
-        delay         = …
-
-### Conditions
-
-    <condition> = <value>
-
-        eg: deny  hosts = !192.168.3.8  # neg. Liste
-            deny !hosts = 192.168.3.8   # neg. Resultat
-
-        vs: deny !verify = recipient    # works
-            deny  verify = !recipient   # FALSCH
-
-
-    Wert der Condition und von Modifiern wird expandiert.
-    Force Failure bedeutet: Condition war nicht anwesend!
-
-    Reihenfolge ist wichtig! Short Circuit.
-    Position der Modifier ist wichtig!
