It deviates +# considerably from what could be considered a standard exim configuration. + +# This configuration file brings in the necessary information from +# other databases stored in /etc/exim/ and the files distributed by ud-ldap + +# This file is independent of the local host, it should not be changed +# per machine. primary_hostname is used in all places that require per-host +# settings. + +# The configuration files in /etc/exim are as follows: +# locals - This is a list of domains that are considered local. A local +# domain is essential one that deliveries to /var/mail +# will be attempted. The users available for local delivery +# comes from /etc/passwd and /etc/aliases. Wildcards are not +# permitted. +# virtualdomains - This is a list of all virtual domains. A virtual domain +# is much like a local domain, execpt that the delivery location +# and allowed set of users is controlled by a virtual domain +# alias file and not /etc/passwd. Wildcards are permitted +# rcpthosts - recipient hosts or relay domains. This is a list of +# all hosts that we mail exchange for. All domains that list +# this host in their MX records should be listed here. Wildcards +# are permitted. +# relayhosts - Hostnames that can send any arbitarily addressed mail to +# us. This is primarily only usefull for emergancy 'queue +# flushing' operations, but should be populated with a list +# of trusted machines. Wildcards are not permitted +# mailhubdomains - Domains for which we are the MX, but the mail is relayed +# elsewhere. This is designed for use with small volume or +# restricted machines that need to use a smarthost for mail +# traffic. We will relay for them based on ssl cert validation +# but we need to teach exim how to route the mail to them. This is +# that list. + +# Exim's wildcard mechanism is a bit odd in that to say "any address in +# debian.org including debian.org" you must use two patterns, +# *.debian.org +# debian.org +# Also you can only place a * before a . and as the first char in a string. +# Wildcards always match last so they may be used as a catchall. + +# Further details can be found in each of the files. + +# Usefull exim commands: +# exim4 -qf - Try sending all messages right now, including frozen ones +# exim4 -bt foo@blah - Write what exim would do if it saw the address +# Great for testing virtual domains and forward files + +# Special Features for users: +# .forward-foo - is understood as an extension address for bar-foo@cow.com +# .forward-default - is understood to be a catch all for bar-*@cow.com +# .procmailrc - with no .forward file invokes procmail for delivery +# automatically. + +# For virtual domains the first lookup is done against a linear text +# database called 'aliases', then .forward files are consulted. Exim +# filtering is available for these .forward files only. .forward-default +# is the universal catch all for everything not handled. + +# Heuristic check (none bad enough to cause a hard reject, but in aggregate +# will trigger things like rcpt to rate limiting or possibly a reject if +# enough hits are triggered. +# +# value is stored in acl_c1 + +###################################################################### +# MAIN CONFIGURATION SETTINGS # +###################################################################### + +# These options specify the Access Control Lists (ACLs) that +# are used for incoming SMTP messages - after the RCPT and DATA +# commands, respectively. + +acl_smtp_helo = check_helo +acl_smtp_rcpt = ${if ={$interface_port}{587} {check_submission}{check_recipient}} +acl_smtp_data = check_message + +# accept domain literal syntax in e-mail addresses.
