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

goetzi · Post by **goetzi** » Tue Feb 05, 2008 5:38 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:
[QUOTE][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:

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?

Yes.

[QUOTE]Does this thread shed any light on the problem?[/QUOTE]

No. The strange thing is that no all mails are deferred, only the ones for @schuelerunion.at.
[QUOTE]I assume that all your DNS records & /etc/hosts file are correct for that domain name?[/QUOTE]

Yes.

[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 · Post by **goetzi** » Tue Feb 05, 2008 6:58 am

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

[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

[QUOTE]content_filter = smtp-amavis:[127.0.0.1]:10024[/QUOTE]
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.

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?

[QUOTE]Is your server currently still up?[/QUOTE]

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

phoenix · Post by **phoenix** » Tue Feb 05, 2008 7:35 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):
host `hostname`
dig yourdomain.com mx

dig yourdomain.com anyjust for my own peace of mind.

[QUOTE]how did you move Zimbra to the new server?[/QUOTE]

- 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

[zimbra@zimbra ~]$ host `hostname`

zimbra.schuelerunion.at has address 78.46.48.66

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