#                  Runtime configuration file for Exim               #
######################################################################


# This is a default configuration file which will operate correctly in # uncomplicated installations. Please see the manual for a complete list # of all the runtime configuration options that can be included in a # configuration file. There are many more than are mentioned here. The # manual is in the file doc/spec.txt in the Exim distribution as a plain # ASCII file. Other formats (PostScript, Texinfo, HTML, PDF) are available # from the Exim ftp sites. The manual is also online at the Exim web sites.


# This file is divided into several parts, all but the first of which are # headed by a line starting with the word "begin". Only those parts that # are required need to be present. Blank lines, and lines starting with # # are ignored.

# Whenever you change Exim's configuration file, you *must* remember to    #
# HUP the Exim daemon, because it will not pick up the new configuration   #
# until you do. However, any other Exim processes that are started, for    #
# example, a process started by an MUA in order to send a message, will    #
# see the new configuration as soon as it is in place.                     #
#                                                                          #
# You do not need to HUP the daemon for changes in auxiliary files that    #

#                    MAIN CONFIGURATION SETTINGS                     #
######################################################################

# Specify your host's canonical name here. This should normally be the fully # qualified "official" name of your host. If this option is not set, the # uname() function is called to obtain the name. In many cases this does # the right thing and you need not set anything explicitly.

# primary_hostname =


# The next three settings create two lists of domains and one list of hosts.
# These lists are referred to later in this configuration using the syntax # +local_domains, +relay_to_domains, and +relay_from_hosts, respectively. They # are all colon-separated lists:

trusted_users = apache

domainlist local_domains = lanvirtual.cl:lanvirtual.com
domainlist relay_to_domains = lanvirtual.cl:lanvirtual.com
hostlist   relay_from_hosts = 127.0.0.1:localhost.localdomain:localhost:lanvirtual.cl

# Most straightforward access control requirements can be obtained by # appropriate settings of the above options. In more complicated situations, you # may need to modify the Access Control List (ACL) which appears later in this # file.

# The first setting specifies your local domains, for example:
#
#   domainlist local_domains = my.first.domain : my.second.domain
#
# You can use "@" to mean "the name of the local host", as in the default # setting above. This is the name that is specified by primary_hostname, # as specified above (or defaulted). If you do not want to do any local # deliveries, remove the "@" from the setting above. If you want to accept mail # addressed to your host's literal IP address, for example, mail addressed to # "user@[192.168.23.44]", you can add "@[]" as an item in the local domains # list. You also need to uncomment "allow_domain_literals" below. This is not # recommended for today's Internet.

# The second setting specifies domains for which your host is an incoming relay.
# If you are not doing any relaying, you should leave the list empty. However, # if your host is an MX backup or gateway of some kind for some domains, you # must set relay_to_domains to match those domains. For example:
#
# domainlist relay_to_domains = *.myco.com : my.friend.org # # 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 third setting specifies hosts that can use your host as an outgoing relay # to any other host on the Internet. Such a setting commonly refers to a # complete local network as well as the localhost. For example:
#
# hostlist relay_from_hosts = 127.0.0.1 : 192.168.0.0/16 # # The "/16" is a bit mask (CIDR notation), not a number of hosts. Note that you # have to include 127.0.0.1 if you want to allow processes on your host to send # SMTP mail by using the loopback address. A number of MUAs use this method of # sending mail.


# All three of these lists may contain many different kinds of item, including # wildcarded names, regular expressions, and file lookups. See the reference # manual for details. The lists above are used in the access control list for # incoming messages. The name of this ACL is defined here:

acl_smtp_rcpt = acl_check_rcpt

# You should not change that setting until you understand how ACLs work.

# The following ACL entries are used if you want to do content scanning with # the exiscan-acl patch. When you uncomment one of these lines, you must also # review the respective entries in the ACL section further below.

# acl_smtp_mime = acl_check_mime
acl_smtp_data = acl_check_content

# This configuration variable defines the virus scanner that is used with # the 'malware' ACL condition of the exiscan acl-patch. If you do not use # virus scanning, leave it commented. Please read doc/exiscan-acl-readme.txt # for a list of supported scanners.

# av_scanner = sophie:/var/run/sophie
av_scanner = clamd:127.0.0.1 3310
# The following setting is only needed if you use the 'spam' ACL condition # of the exiscan-acl patch. It specifies on which host and port the SpamAssassin # "spamd" daemon is listening. If you do not use this condition, or you use # the default of "127.0.0.1 783", you can omit this option.

spamd_address = 127.0.0.1 783

# Specify the domain you want to be added to all unqualified addresses # here. An unqualified address is one that does not contain an "@" character # followed by a domain. For example, "caesar@rome.example" 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 recipient_unqualified_hosts option 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 =


# The following line must be uncommented if you want Exim to recognize # addresses of the form "user@[10.11.12.13]" that is, with a "domain literal"
# (an IP address) instead of a named domain. The RFCs still require this form, # but it makes little sense to permit mail to be sent to specific hosts by # their IP address in the modern Internet. This ancient format has been used # by those seeking to abuse hosts by using them for unwanted relaying. If you # really do want to support domain literals, uncomment the following line, and # see also the "domain_literal" router below.

# allow_domain_literals


# No deliveries will ever be run under the uids of these users (a colon- # separated list). An attempt to do so causes a panic error to be logged, and # the delivery to be deferred. This is a paranoic safety catch. There is an # even stronger safety catch in the form of the FIXED_NEVER_USERS setting # in the configuration for building Exim. The list of users that it specifies # is built into the binary, and cannot be changed. The option below just adds # additional users to the list. The default for FIXED_NEVER_USERS is "root", # but just to be absolutely sure, the default here is also "root".

# Note that 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.

never_users = 


# 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 = *


# The settings below, which are actually the same as the defaults in the # code, cause Exim to make RFC 1413 (ident) callbacks for all incoming SMTP # calls. You can limit the hosts to which these calls are made, and/or change # the timeout that is used. If you set the timeout to zero, all RFC 1413 calls # are disabled. RFC 1413 calls are cheap and can provide useful information # for tracing problem messages, but some hosts and firewalls have problems # with them. This can result in a timeout instead of an immediate refused # connection, leading to delays on starting up an SMTP session.

rfc1413_hosts = *
rfc1413_query_timeout = 0s


# 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 # # sender_unqualified_hosts = # recipient_unqualified_hosts = # # to control sender and recipient addresses, respectively. When this is done, # unqualified addresses are qualified using the settings of qualify_domain # and/or qualify_recipient (see above).


# If you want Exim to support the "percent hack" for certain domains, # uncomment the following line and provide a list of domains. The "percent # hack" is the feature by which mail addressed to x%y@z (where z is one of # the domains listed) is locally rerouted to x@y and sent on. If z is not one # of the "percent hack" domains, x%y is treated as an ordinary local part. This # hack is rarely needed nowadays; you should not enable it unless you are sure # that you really need it.
#
# percent_hack_domains =
#
# As well as setting this option you will also need to remove the test # for local parts containing % in the ACL definition below.


# When Exim can neither deliver a message nor return it to sender, it "freezes"
# the delivery error message (aka "bounce message"). There are also other # circumstances in which messages get frozen. They will stay on the queue for # ever unless one of the following options is set.

# This option unfreezes frozen bounce messages after two days, tries # once more to deliver them, and ignores any delivery failures.

ignore_bounce_errors_after = 2d

# This option cancels (removes) frozen messages that are older than a week.

timeout_frozen_after = 7d

# This option, if uncommented, allows Exim to listen on ports other than # just the default port 25. For example, you may wish Exim to sldo listen # on the 'message submission' port 587 for roaming clients which cannot # use port 25 directly from their current location. (cf. RFC 2476).
#
# daemon_smtp_ports = smtp : msa

# This option instructs Exim to advertise the availability of encrypted # connections to all hosts, and uses the certificate which is automatically # generated when the RPM is installed. You can disable TLS, should you need # to do so, by commenting out the three lines below.

tls_advertise_hosts = *
tls_certificate = /usr/share/ssl/certs/exim.pem tls_privatekey = /usr/share/ssl/private/exim.pem

# This setting, if uncommented, allows users to authenticate using # their system passwords against saslauthd if they connect over a # secure connection. If you have network logins such as NIS or # Kerberos rather than only local users, then you possibly also want # to configure /etc/sysconfig/saslauthd to use the 'pam' mechanism # too. Once a user is authenticated, the acl_check_rcpt ACL then # allows them to relay through the system. 
#
# auth_advertise_hosts = ${if eq {$tls_cipher}{}{}{*}} # # By default, we set this option to allow SMTP AUTH from nowhere # (Exim's default would be to allow it from anywhere, even on an # unencrypted connection).

  #############################################################################
  # The following section of the ACL is concerned with local parts that contain
  # @ or % or ! or / or | or dots in unusual places.
  #
  # The characters other than dots are rarely found in genuine local parts, but
  # are often tried by people looking to circumvent relaying restrictions.
  # Therefore, although they are valid in local parts, these rules lock them
  # out, as a precaution.
  #
  # Empty components (two dots in a row) are not valid in RFC 2822, but Exim
  # allows them because they have been encountered. (Consider local parts
  # constructed as "firstinitial.secondinitial.familyname" when applied to
  # someone like me, who has no second initial.) However, a local part starting
  # with a dot or containing /../ can cause trouble if it is used as part of a
  # file name (e.g. for a mailing list). This is also true for local parts that
  # contain slashes. A pipe symbol can also be troublesome if the local part is
  # incorporated unthinkingly into a shell command line.
  #
  # Two different rules are used. The first one is stricter, and is applied to
  # messages that are addressed to one of the local domains handled by this
  # host. It blocks local parts that begin with a dot or contain @ % ! / or |.
  # If you have local accounts that include these characters, you will have to
  # modify this rule.

  # The second rule applies to all other domains, and is less strict. This
  # allows your own users to send outgoing messages to sites that use slashes
  # and vertical bars in their local parts. It blocks local parts that begin
  # with a dot, slash, or vertical bar, but allows these characters within the
  # local part. However, the sequence /../ is barred. The use of @ % and ! is
  # blocked, as before. The motivation here is to prevent your users (or
  # your users' viruses) from mounting certain kinds of attack on remote sites.

When this configuration is installed automatically, # the name gets inserted into this file from whatever is set in Exim's # build-time configuration. The default path is the traditional /etc/aliases.
# If you install this configuration by hand, you need to specify the correct # path in the "data" setting below.
#
##### NB  You must ensure that the alias file exists. It used to be the case ##### NB  that every Unix had that file, because it was the Sendmail default.
##### NB  These days, there are systems that don't have it. Your aliases ##### NB  file should at least contain an alias for "postmaster".
#
# 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 the transports # 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.

   driver = redirect

# This router handles forwarding using traditional .forward files in users'
# home directories. If you want it also to allow mail filtering when a forward # file starts with the string "# Exim filter" or "# Sieve filter", uncomment # the "allow_filter" option.

# If you want this router to treat local parts with suffixes introduced by "-"
# or "+" characters as if the suffixes did not exist, uncomment the two local_ # part_suffix options. Then, for example, xxxx-foo@your.domain will be treated # in the same way as xxxx@your.domain by this router. You probably want to make # the same change to the localuser router.

# The no_verify setting means that this router is skipped when Exim is # verifying addresses. Similarly, no_expn means that this router is skipped if # Exim is processing an EXPN command.

# 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.
