multi-domain configuration - mail loops back

[segleaur]

hey guys, i just started hosting a secondary domain on my server, using zimbra 4.5, and everything is fine in the primary domain (domain1.com), but when i try to send mail to the internal users (userxxx@domain2.com), i get a message saying:

: mail for domian2.com loops back to myself

there's nothing for the external relay, and the smtp server globally is set to smtp.domain1.com. i can send from domain2.com to domain1.com without a problem. domain2.com can send e-mail to external accounts, but i can't send to anyone @domain2.com.

any ideas?

there's nothing for the external relay

1 physical (ok or virtual) server-with two domains in zimbra correct? Try setting all the MTA settings-in BOTH the server individual mta tab and the global mta tab to 'localhost' is.
-that would be 4 blanks both 'webmail mta' and 'relay mta external delivery' all set to 'localhost'

[segleaur]

because originally, there wasn't going to be a second domain hosted on the same server. that kinda crept up in the last few days. if setting the external mta was in the instructions, i missed it, but without the setting, it worked fine.

[mmorse]

welp-set them all to localhost and see what happens i guess

[segleaur]

now all e-mail is being deferred on both domains (unless it's domain1 to domain1 or domain2 to domain1; everything to domain2 is being deferred). webmail MTA and external MTA are both set to localhost. The error mesage is saying that mail delivery is being temporarily suspended: mail to localhost loops back to myself.

hmmmmmm....

Update:

OK, so I've played around with the settings a bit:

1.- If i don't have anything in the external MTA field, mail will bounce back to the user (me, let's say) saying that mail can't be delivered because it loops back to itself. This is only if it's domain2.com to domain2.com. domain2.com to anywhere else works.
2.- If i put localhost/smtp.domain1.com (which is the same server)/domain2.com, mail will get stuck in the deferred queue with the same error message: loops back to itself.

if i do a dig for domain1.com:

both reside on the server, which is also the DNS server.

externally, domain2.com looks like:

it doesn't look like a dns problem to my untrained eye in these matters. any ideas?

[segleaur]

I forgot to mention, setting both the webmail MTA and the external relay host causes the same problems are option 1 above. So, I'm fresh out of ideas. Is there anyone out there that is running a single server setup with two or more virtual hosts?

[jholder]

Take a look at your hosts file. Can you post that?

[segleaur]

sure thing:

##
# Host Database
#
# localhost is used to configure the loopback interface
# when the system is booting.  Do not change this entry.
##
127.0.0.1       localhost
255.255.255.255 broadcasthost
::1             localhost

# Local IPs
192.168.13.13   smtp.mechanus.org imap.mechanus.org www.mechanus.org webmail.mechanus.org animus.mechanus.org ftp.mechanus.org stats.mechanus.org sigil.mechanus.org www.eskinaproductions.com webmail.eskinaproductions.com sigil.eskinaproductions.com

[jholder]

Try reverting any config you have in this thread, and only make the hosts file
xxx.xxx.xxx.xxx hostname.domain.com

The actual hostname. The rest should be up to DNS.

[segleaur]

ok, so the server is now configured with its own hostname in the hosts file (192.168.13.13 sigil.mechanus.org), dns is unchanged. and the webmail UI is: webmail MTA: smtp.mechanus.org and external relay is localhost. but no dice. i get a relay error from my test gmail account:

Delivery to the following recipient failed permanently:

Technical details of permanent failure:
