Mail deferred with Connection timed out

[Miklos Kalman]

Hi,

I recently setup another server with Zimbra (this time a FOSS version). Everything went smooth. The server can receive email without any trouble. When trying to send however I get the following error on the web client:

The email is queued in the mailserver and never gets delivered. I am trying to send to a gmail account.


Looking at the logs I get this message:

That server may be down, try a connection via telnet to that IP on port 25 and see what the response is. You may also be trying to connect to the wrong IP, I don't believe that's the google smtp server. You should also check there's no outbound blocking of port 25 i.e. no firewall and/or SElinux.

Please don't post a ton of logs in the forums unless you're asked to. I've already given you a test to try from the 'failing' server, have you tried a telnet to that ip shown in the logs? Have you also checked the firewall, SElinux and any outbound blocks on port 25?

Hi, Sorry for the long paste. The server doesn't have SELinux enabled, nor a firewall and nothing is blocking port 25 as it can deliver to my other server's addresses. The other server takes a different approach to delivering the email to a gmail account. It is full of slapd calls, whereas the new server just tries to connect and fails. What could be causing this.

Thanks,
Miklos

I have also tried to send mail to a yahoo email account but receive the same error:

Dec 21 17:03:03 mail postfix/smtp[17479]: 34E9F6A7031E: to=<account@yahoo.com>, relay=none, delay=60, delays=0.01/0/60/0, dsn=4.4.1, status=deferred (connect to yahoo.com[206.190.60.37]: Connection timed out)

Please help.

Thanks,
Miklos

The same effect also happens when trying to send mail to other locations like yahoo.com, gmail.com, hushmail.com. They all get deferred with a connection timeout.

Any ideas? Please help since I am really stuck on this one.

Thanks,
Miklos
