Sujet: [exim] Urouteable address when send from remote host
Hi,

The following is the situation, a server (CentoS + DirectAdmin) where Exim is installed should route mails for a certain domain (example.com) to Domino/Notes which is running on the same machine on a different port (26).

# snippet /etc/exim.conf

# router
domino_notes_route:
  transport       = domino_notes_smtp
  driver          = manualroute
  domains         = example.com
  route_list      = * 127.0.0.1
  no_verify
  self = send


# transport
domino_notes_smtp:
driver = smtp
hosts = 127.0.0.1
port = 26


# exim -bt user@???
user@???
router = domino_notes_route, transport = domino_notes_smtp
host 127.0.0.1 [127.0.0.1]

When I run the following command on the local machine:

echo "hi” | mail -s "ho” user@???

I get:

014-04-24 19:32:46 1WdNVu-0002OO-C7 <= root@??? U=root P=local S=510 T="ho" from <root@???> for user@???
2014-04-24 19:32:46 1WdNVu-0002OO-C7 => user@??? F=<root@???> R=domino_notes_route T=domino_notes_smtp S=528 H=127.0.0.1 [127.0.0.1] C="250 Message accepted for delivery"
2014-04-24 19:32:46 1WdNVu-0002OO-C7 Completed

Which looks good, but when i run the same command from a remote host, I get:

2014-04-24 19:36:09 H=mail.somedomain.com [1.1.1.1] F=<user@???> rejected RCPT <user@???>: Unrouteable address
2014-04-24 19:36:09 H=mail.somdomain.com [1.1.1.1] incomplete transaction (RSET) from <user@???>

Any idea what’s going on?

# Whenever you change Exim's configuration file, you *must* remember #

# 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.                                                             #

# The following line prevents Exim from recognizing addresses of the form
# "user@???" 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, and 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, remove the following line, and see

# 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

# DO HOST LOOKUP
# OPTIONAL MODIFICATIONS:
# 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.

# DISALLOW IDENT CALLBACKS
# OPTIONAL MODIFICATIONS:
# Exim may be set 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. By default
# we disable callbacks for incoming SMTP calls. You may change
# rfc1413_query_timeout to 30s or some other positive number of seconds to
# enable callbacks for incoming SMTP calls.

rfc1413_hosts = *
rfc1413_query_timeout = 0s

# BOUNCE MESSAGES
# OPTIONAL MODIFICATIONS:
# 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 forever unless one or both of the following options is set.

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

# This option cancels (removes) frozen messages that are older than five days.
