[SOLVED] Moved zimbra to new server - mail gets deferred

**goetzi** · 02-05-2008, 03:38 AM

Hi,

I moved my Zimbra install to a new server this night. Now I have the problem that all emails get into the deferred queue with the error "mail transport unavailable".

Here the zimbra.log of one example message sent from outside:

[zimbra@zimbra opt]$ tail -n 2000 /var/log/zimbra.log | grep 665171A74BFA

One thing is very interesting: that only happens for the domain schuelerunion.at

The delivery to another domain (michael@glatter-goetz.de which is an alias of michael.glatter-goetz@schuelerunion.at) works fine:

[zimbra@zimbra opt]$ tail -n 2000 /var/log/zimbra.log | grep 3DNDm0GPUI4K

Feb 5 12:29:48 zimbra postfix/qmgr[31926]: 25C441A74BF9: removed

What can this be? I don't know why the mails are not delivered and this is a real showstopper.

Please help me!

Are all the zimbra services up and running? Does this thread shed any light on the problem? I assume that all your DNS records & /etc/hosts file are correct for that domain name?

**goetzi** · 02-05-2008, 04:01 AM

Are all the zimbra services up and running?

Yes.

Code:

[zimbra@zimbra ~]$ zmcontrol start
Host zimbra.schuelerunion.at
        Starting ldap...Done.
        Starting logger...Done.
        Starting mailbox...Done.

        Starting snmp...Done.

        Starting mta...Done.
        Starting stats...Done.
[zimbra@zimbra ~]$ zmcontrol status

        stats                   Running
[zimbra@zimbra ~]$

Does this thread shed any light on the problem?

No. The strange thing is that no all mails are deferred, only the ones for @schuelerunion.at.

I assume that all your DNS records & /etc/hosts file are correct for that domain name?

Yes.

Code:

[zimbra@zimbra ~]$ cat /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1       localhost.localdomain  localhost
78.46.48.66     zimbra.schuelerunion.at zimbra
#::1            localhost6.localdomain6 localhost6

I can give you root/Zimbra admin access if needed.

Maybe can you try what is in this post : Strange Transport Problem - list.postfix.users | Google Groups

**goetzi** · 02-05-2008, 04:58 AM

Hm... if I want to do a postcat -q I get:

Code:

[zimbra@zimbra ~]$ postcat -q D17F51A74C90
postcat: fatal: open queue file D17F51A74C90: Permission denied

in /opt/zimbra/postfix/conf/main.cf the content_filter line is

content_filter = smtp-amavis:[127.0.0.1]:10024

Disabling Antispam and Antivirus has no effect.

I have no idea what to do.
As said before, if you want root access to the machine you can get it.

**phoenix** · 02-05-2008, 05:08 AM

Is your server currently still up? I can't get a connection to it from here, you don't have any firewall oir SElinux active do you?

**goetzi** · 02-05-2008, 05:11 AM

Is your server currently still up?

I did a restart at this moment. Server is up again.

**phoenix** · 02-05-2008, 05:35 AM

Just out of interest, how did you move Zimbra to the new server? Could you post the output of the following commands (run on the zimbra server):

Code:

host `hostname`  <-- type as-is and use backticks not single quotes
dig yourdomain.com mx 
dig yourdomain.com any

just for my own peace of mind.

**goetzi** · 02-05-2008, 05:42 AM

how did you move Zimbra to the new server?

- Old server was NE 4.5.5 on CentOS4 x86
- Installed NE 4.5.6 on the new machine (CentOS5 x86)
- blocked port 25 on old server (mails were queued on secondary MX)
- made full backup of old server (using zmbackup)
- created domains on new server
- restored full backup on new machine
- updated to NE 5.0.2
- changed MX entry fitting to the new server

host `hostname`

Code:

[zimbra@zimbra ~]$ host `hostname`
zimbra.schuelerunion.at has address 78.46.48.66

dig yourdomain.com mx

Code:

[zimbra@zimbra ~]$ dig schuelerunion.at mx

It would appear from those results that you don't have an A record, you need one (unless you'#re only posting partial details?).
