# Specify the domain you want to be added to all unqualified addresses
# here. 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 = dummy-domain.snd.x

# 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 = dummy-domain.rcp.x

# 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.

local_domains = 

# Allow mail addressed to our hostname, or to our IP address.

local_domains_include_host = true
local_domains_include_host_literals = true

# Domains we relay for; that is domains that aren't considered local but we 
# accept mail for them.

#relay_domains = 

# If this is uncommented, we accept and relay mail for all domains we are 
# in the DNS as an MX for.

#relay_domains_include_local_mx = true

# 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.

never_users = root

# 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 setting below would, if uncommented, cause Exim to check the syntax of
# all the headers that are supposed to contain email addresses (To:, From:,
# etc). This reduces the level of bounced bounces considerably.

headers_check_syntax

# Exim contains support for the Realtime Blocking List (RBL), and the many
# similar services that are being maintained as part of the DNS. See 
# http://www.mail-abuse.org/ for background. The line below, if uncommented,
# will reject mail from hosts in the RBL, and add warning headers to mail
# from hosts in a list of dynamic-IP dialups. Note that MAPS may charge
# for this service.

#rbl_domains = rbl.mail-abuse.org/reject : dialups.mail-abuse.org/warn

# The setting below allows your host to be used as a mail relay only by
# localhost and anything in the 192.168.1.255 subnet - you'll need to
# drop your network in here (or you can just open it up - hell, it's a
# bitbucket - if a spammer picks it up, you'll actually be _reducing_
# spam ) :

host_accept_relay = 127.0.0.1 : ::::1 : 192.168.1.0/24

# This setting allows anyone who has authenticated to use your host as a
# mail relay. To use this you will need to set up some authenticators at
# the end of the file

host_auth_accept_relay = *

# 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

# percent_hack_domains=*

# If this option is set, then any process that is running as one of the
# listed users may pass a message to Exim and specify the sender's
# address using the "-f" command line option, without Exim's adding a
# "Sender" header.

trusted_users = mail

# If this option is true, the SMTP command VRFY is supported on incoming
# SMTP connections; otherwise it is not.

smtp_verify = true

# Some operating systems use the "gecos" field in the system password file
# to hold other information in addition to users' real names. Exim looks up
# this field when it is creating "sender" and "from" headers. If these options
# are set, exim uses "gecos_pattern" to parse the gecos field, and then
# expands "gecos_name" as the user's name. $1 etc refer to sub-fields matched
# by the pattern.

gecos_pattern = ^([^,:]*)
gecos_name = $1

# This sets the maximum number of messages that will be accepted in one
# connection. The default is 10, which is probably enough for most purposes,
# but is too low on dialup SMTP systems, which often have many more mails
# queued for them when they connect.

smtp_accept_queue_per_connection = 100

# Send a mail to the postmaster when a message is frozen. There are many
# reasons this could happen; one is if exim cannot deliver a mail with no
# return address (normally a bounce) another that may be common on dialup
# systems is if a DNS lookup of a smarthost fails. Read the documentation
# for more details: you might like to look at the auto_thaw option

freeze_tell_mailmaster = true

# This string defines the contents of the \`Received' message header that
# is added to each message, except for the timestamp, which is automatically
# added on at the end, preceded by a semicolon. The string is expanded each
# time it is used.

received_header_text = "Received: \
         ${if def:sender_rcvhost {from ${sender_rcvhost}\n\t}\
         {${if def:sender_ident {from ${sender_ident} }}\
         ${if def:sender_helo_name {(helo=${sender_helo_name})\n\t}}}}\

         ${if def:received_for {\n\tfor <$received_for>}}"

# This would make exim advertise the 8BIT-MIME option. According to
# RFC1652, this means it will take an 8bit message, and ensure it gets
# delivered correctly. exim won't do this: it is entirely 8bit clean
# but won't do any conversion if the next hop isn't. Therefore, if you
# set this option you are asking exim to lie and not be RFC
# compliant. But some people want it.

#accept_8bitmime = true

# This will cause it to accept mail only from the local interface
