+# This is the main exim4 configuration file based on the 28.08.05 version by
+# ametzler
+# It is hand crafted, do not replace with anything generated by a config
+# tool!
+# It is installed as part of the debian.org package -- don't edit this file
+
+# The configuration file uses a set of macros and rules to generate an
+# acceptable mail environment for debian.org machines. 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/ right now these are linear text
+# databases.
+
+# 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
+# The division of files is designed so that all hosts may share rcpthosts
+# and relayhosts, these could be replicated automatically if necessary.
+
+# 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.
