Cannot receive email due to host not found error.

Zimbra V 5.03 on SLES 9.1

Going crazy with this one and I know people are going to say 'check your dns'. I have spent hours checking the DNS and hosts. If I turn on "Enable DNS lookups", then all incoming email gets bounced with the following error.

Mail Error:
to=, relay=none, delay=10, delays=0.2/0.04/10/0, dsn=5.4.4, status=bounced (Host or domain name not found. Name service error for name=msp.domain.local type=A: Host not found)

Test Results are:

Hosts:
192.168.2.3 msp.domain.local msp

DNS:
dig mx domain.local -> msp.domain.local
dig msp.domain.local -> 192.168.2.3

Host:
host msp.domain.local
msp.domain.local has address 192.168.2.3
msp.domain.local mail is handled by 10 msp.domain.local.

All tests seem to prove the DNS is working but somehow Zimbra/postfix can't resolve an A record for the mail server? This doesn't seem to make any sense. Any clues or help much appreciated.

Thanks

Do the following on the zimbra server and post the results:

host `hostnamea  <-- type as-is and use backticks not single quotes
dig .domain.local mx
dig .domain.local any

[moedaellc]

msp:/ # host 'msp.domain.local'
msp.domain.local has address 192.168.2.3
msp.domain.local mail is handled by 10 msp.domain.local.

msp:/ # dig domain.local  mx

That wasn't quite what I asked for, do thie following command exactly as I've typed it:

host `hostname`

and while we're at it you might as well post the output of the collowing:

cat /etc/hosts

I notice from your first post that you say that you're installed on SLES9.1, I guess you know that it's EOL and therefore an unsupported platform for NE? Is this an NE install or OSS?

I made a mistake on the version in my post. This problem is on SLES10. I have too many instances to list them all in the profile. I do need to update the Zimbra versions in my profile as the Zimbra instances are now at 5.0.3 or 4 or 5.

Apparently I sometimes have trouble following directions. Here is the host results hopefully exactly as requested.

msps2@msp:~> host `hostname`
msp.domain.local has address 192.168.2.3
msp.domain.local mail is handled by 10 msp.domain.local.

msps2@msp:~> cat /etc/hosts
#
# hosts         This file describes a number of hostname-to-address
#               mappings for the TCP/IP subsystem.  It is mostly
#               used at boot time, when no name servers are running.
#               On small systems, this file can be used instead of a

192.168.2.3     msp.domain.local msp
192.168.2.4     mail.domain.local mail

Note the mail.domain.local is not used. Zimbra is provisioned as msp.domain.local.

I do vaguely recall from a couple of years ago that there was some Bind or Samba bug in SLES9.1 regarding using a domain name with a .local suffix. This is the only one of the Zimbra instances I have running on a .local TLD.

Thanks

You need to modify the hosts file, change this:

127.0.0.1       localhost

to this:

127.0.0.1       localhost.localdomain localhost

and restart the server. Do you have any firewall and/or AppArmor installed or active on this server?

[moedaellc]

I can't restart the server until this evening. I will make the suggested changes then and let you know what happens.

Thanks
