######################################################################
# This is a default configuration file which will operate correctly in

# of all the runtime configuration options that can be included in a

# 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

# followed by a domain. For example, "caesar@rome.ex" is a fully qualified
# 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.
# qualify_domain =
# If you want unqualified recipient addresses to be qualified with a different
# domain to unqualified sender addresses, specify the recipient domain here.
# If this option is not set, the qualify_domain value is used.
# qualify_recipient =
# 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.

# following line, or supply the literal domain(s) as part of "local_domains"
# above.

# 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.

# 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.

# starts with the string "# Exim filter", uncomment the "filter" option.
# The check_ancestor option means that if the forward file generates an
# address that is an ancestor of the current one, the current one gets
# passed on instead. This covers the case where A is aliased to B and B
# has a .forward file pointing to A. The three transports specified at the
# end are those that are used when forwarding generates a direct delivery
# to a file, or to a pipe, or sets up an auto-reply, respectively.

# This transport is used for local delivery to user mailboxes. By default
# it will be run under the uid and gid of the local user, and requires
# the sticky bit to be set on the /var/mail directory. Some systems use
# the alternative approach of running mail deliveries under a particular
# group instead of using the sticky bit. The commented options below show
# how this can be done.
# This transport is used for handling pipe deliveries generated by alias
# or .forward files. If the pipe generates any standard output, it is returned
# to the sender of the message as a delivery error. Set return_fail_output
# instead of return_output if you want this to happen only when the pipe fails
# to complete normally. You can set different transports for aliases and
# forwards if you want to - see the references to address_pipe below.
