-# Welche Konfiguration wird eingelesen?
-
-    > exim -bV | tail -n 1
-    TODO: exim -be '$config_file'
-
-# Wann wird die Konfiguration eingelesen?
-
-    - Klar - beim Start
-    - Aber - wann wird gestartet?
-        - Start Daemon
-        - Signal HUP
-        - re-exec for verschiedene Zwecke
-    - Achtung: 
-        - exim4.conf + .include ist "statisch"
-        - lists, lookups, … "dynamisch"
-    - Config-Parser: nur simple Syntax-Checks
-    - trim, "de-comment"
-
-# Syntax der Konfiguration

-## Macros und …
-    - Macros - Text-Ersatz während des Einlesens,

-
-    Quoting für \\, \n, \r, \t, \ddd, \xdd und führende oder baumelnde Spaces
-
-    - Vorsicht: Expansion
-    - Vorsicht: User/Groups
-

-
-
-### 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
-
-    > exim -be '-be '${map{<, ,a,b,,, ,c,}{<$item>}}'
-
-### 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: sqlite;/etc/db.sqlite SELECT … WHERE ${quote_sqlite:$local_part} …
-                                        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.
-
-### 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}...}
