   1 EXIM ALIAS AND LOCAL DOMAIN CONFIGURATION
   2
   3
   4 This module implements handling of e-mail aliases and configuring
   5 domains for which e-mail should be accepted locally for the exim MTA
   6 (http://www.exim.org).
   7
   8 A .aliases file in a domain's directory controls its e-mail
   9 aliases. A target below may one of three things:
  10
  11  * a local username, to deliver mail to that user
  12  * an e-mail address, to forward mail to it
  13  * !, to delete mail to this address
  14
  15 The file then consists of a sequence of lines of the following types.
  16
  17  * user target: Send all mail to user@domain to target
  18  * * target: Send all mail to domain not matching any other rule
  19 to target. However, if mail is sent to an existing UNIX username on
  20 Abulafia, the message will go to that account
  21  * ** target: Send all mail that does not match another rule to
  22 domain to target, even mail addressed to real UNIX usernames
  23
  24 These policies are implemented by writing to two different alias files
  25 which are meant to be processed in different passes. The first one
  26 (probably /etc/aliases) should be check before exim checks an e-mail
  27 recipient against local useranmes or other special targets. After
  28 this, local usernames should be checked. Finally, the second alias
  29 file (such as /etc/aliases.default) should be checked, to implement
  30 "catch-all" addresses that handle all mail not matching other rules.
  31

  33 The module also handles receiving notifications of which domains
  34 delegate mail handling to this host and incorporating this information
  35 into exim configuration files. A file local_domains is maintained in
  36 the domtool scratchDir, along with the last version of it in
  37 local_domains.last, to detect when changes have been made. The module
  38 will attempt to generate exim.conf by concatenatning local_domains and
  39 a file exim.base. The paths for these files are configurable in
  40 config.sml, as is the command used to tell exim to reload exim.conf
  41 afterwards.
