# manual is in the file doc/spec.txt in the Exim distribution as a plain
# ASCII file. Other formats (PostScript, Texinfo, HTML) are available from
# the Exim ftp sites. The manual is also online via the Exim web sites.


# This file is divided into several parts, all but the last of which are
# terminated by a line containing the word "end". The parts must appear
# in the correct order, and all must be present (even if some of them are
# in fact empty). Blank lines, and lines starting with # are ignored.

# address, but the string "caesar" (i.e. just a login name) is an unqualified
# email address. Unqualified addresses are accepted only from local callers by
# default. See the receiver_unqualified_{hosts,nets} options if you want
# to permit unqualified addresses from remote sources. If this option is
# not set, the primary_hostname value is used for qualification.

# Specify your local domains as a colon-separated list here. If this option
# is not set (i.e. not mentioned in the configuration file), the
# qualify_recipient value is used as the only local domain. If you do not want
# to do any local deliveries, uncomment the following line, but do not supply
# any data for it. This sets local_domains to an empty string, which is not
# the same as not mentioning it at all. An empty string specifies that there
# are no local domains; not setting it at all causes the default value (the
# setting of qualify_recipient) to be used.

# No local deliveries will ever be run under the uids of these users (a colon-
# separated list). An attempt to do so gets changed so that it runs under the
# uid of "nobody" instead. This is a paranoic safety catch. Note the default
# setting means you cannot deliver mail addressed to root as if it were a
# normal user. This isn't usually a problem, as most sites have an alias for
# root that redirects such mail to a human administrator.

#
# If you want to permit relaying through your host from certain hosts or IP
# networks, you need to set the option appropriately, for example
#
#
#
# If you are an MX backup or gateway of some kind for some domains, you must
# set relay_domains to match those domains. This will allow any host to
# relay through your host to those domains.
#
# See the section of the manual entitled "Control of relaying" for more
# information.

# The setting below causes Exim to do a reverse DNS lookup on all incoming
# IP calls, in order to get the true host name. If you feel this is too
# expensive, you can specify the networks for which a lookup is done, or
# remove the setting entirely.

#host_lookup = 0.0.0.0/0


# By default, Exim expects all envelope addresses to be fully qualified, that
# is, they must contain both a local part and a domain. If you want to accept
# unqualified addresses (just a local part) from certain hosts, you can specify
# these hosts by setting one or both of
#
# receiver_unqualified_hosts =
# sender_unqualified_hosts =
#
# to control sender and receiver addresses, respectively. When this is done,
# unqualified addresses are qualified using the settings of qualify_domain
# and/or qualify_recipient (see above).


# Exim contains support for the Realtime Blocking List (RBL) that is being
# maintained as part of the DNS. See http://maps.vix.com/rbl/ for background.
# Uncommenting the first line below will make Exim reject mail from any
# host whose IP address is blacklisted in the RBL at maps.vix.com. Some
# others have followed the RBL lead and have produced other lists: DUL is
# a list of dial-up addresses, and ORBS is a list of open relay systems. The
# second line below checks all three lists.

# rbl_domains = rbl.maps.vix.com
# rbl_domains = rbl.maps.vix.com


# If you want Exim to support the "percent hack" for all your local domains,
# uncomment the following line. This is the feature by which mail addressed
# to x%y@z (where z is one of your local domains) is locally rerouted to
# x@y and sent on. Otherwise x%y is treated as an ordinary local part.

# Local addresses are those with a domain that matches some item in the

# This director handles aliasing using a traditional /etc/aliases file.
# If any of your aliases expand to pipes or files, you will need to set
# up a user and a group for these deliveries to run under. You can do
# this by uncommenting the "user" option below (changing the user name
# as appropriate) and adding a "group" option if necessary. Alternatively, you
# can specify "user" on the transports that are used. Note that those
# listed below are the same as are used for .forward files; you might want
# to set up different ones for pipe and file deliveries from aliases.

# This single retry rule applies to all domains and all errors. It specifies
# retries every 15 minutes for 2 hours, then increasing retry intervals,
# starting at 1 hour and increasing each time by a factor of 1.5, up to 16
# hours, then retries every 8 hours until 4 days have passed since the first
# failed delivery.
