[SOLVED] Unable to receive incoming email

[ste86]

Hi,

I've been scratching my head over this one for the last few hours, so I hope someone can help.

I've got Zimbra running alongside Plesk on the same server. It's been working fine for several months but this morning stopped accepting incoming mail. I have Plesk set up to listen on port 25 and 2525, with Zimbra's MTA on 25. This config has never been a problem.

I've tried disabling Qmail in Plesk so that only Zimbra is listening on 25 but that's not helped. Telnet'ing to 25 on localhost comes back with:

[root@precision1 xinetd.d]# telnet localhost 25
Trying 127.0.0.1...
Connected to localhost.localdomain (127.0.0.1).
Escape character is '^]'.
220 precision1.precisionstitching.co.uk ESMTP Postfix

The only big thing that's changed is that I updated the rDNS on two IP addresses last night. All standard DNS records are unchanged. Would that stop it from working?

I hope I've provided enough info but please let me know if I've missed anything!


Thanks,

Stephen

Well checking your MX record for that domain gives a different server all together, and when telneting to it I get a connection failure.

Personally I would change your MX setup for your .com and .co.uk ... Decide which was is going to be the primary MX and have the other point to it. So,

precisionstitching.co.uk -> mail.precisionstitching.co.uk
precisionstitching.com -> mail.precisionstitching.co.uk

This will mean your rDNS returns the correct information which it is not doing at the moment

Excellent, thanks for that! I've made the changes... now to wait! *fingers crossed*

Your rDNS was pointing to just the domain name and not the FQDN of your mailserver so how that is sorted aswell
