Cannot receive mails

[zzzzsg]

Hi Everybody

I installed zcs-3.0.0_M2_740.FC3.tgz on Fedora 3.

Everything seems to be working except that I cannot receive any mail, not even mails I send to myself. That is, cannot receive any mail at all. Cannot receive mail from internal Zimbra users, cannot receive mail from external users, e.g. tom@yahoo.com. I can send mails out to non-zimbra accounts though.

When I was using M1 previously, everything was okay - could receive mail.

I checked the /var/log/zimbra.log and found these

Nov 26 16:55:29 servername postfix/lmtp[31552]: 493E92C14B: to=, relay=none, delay=189, status=deferred (connect to servername.mydomainname.com[ip....]: Connection timed out)
Nov 26 16:56:00 servername postfix/qmgr[30039]: 3D1F72C147: from=, size=1118, nrcpt=1 (queue active)

I did a zmcontrol status and everything was running.

Can anybody help?

Thank you very much in anticipation.

Here's what's happening here:

The servername that it's trying to connect to (on port 25) isn't resolving to an IP on your box - does the IP match the server? If it resolves to a port-forwarded firewall IP, is the firewall allowing the connection? (The fact that it's timing out, not being refused, makes me suspect firewall.)

It's possible that you're MX records aren't right - you can try turning off DNS lookups in the MTA, but you'll have to set a relay host, for all outgoing mail.

Also might want to run zmiptables -u to make sure iptables is now disabled.

Yes, turning off DNS works. I forgot I did the same thing on Zimbra 1.
Thank you.
