Confusing bounce behavior 5.0.0

Post by zim_mike »

I am experiencing a rather confusing bounce behavior.
I built a new zimbra server to replace an old one.
I migrated everything from the old server to the new one.
I updated all associated DNS records etc.
Everything seems to work but the domain name which was used as a admin on the old server which I also migrated to the new server.

Emails to this domain come in just fine yet the senders always receive a notification that the email didn't reach the recipient.
Other than the following, there isn't much information to go on. I can see the 5.0.0 but the emails are actually getting int.

Action: failed
Status: 5.0.0
Diagnostic-Code: X-Postfix; mydomain.net

The new server has a new FQDN domain as the master or admin of zimbra if you will.

What could be causing this? Does it have something to do with the fact that I migrated (zetras) the old domain to the new server and now there is some sort of conflict?

You didn't mention re-using the same IP address, and said it was a new host.

Do you have a DNS SPF record setup for the domain?

If so, have you changed this to reflect the new server?

If you look at the headers from the bounced messages (right-click on a message and Show original), what error numbers/messages are listed?

I cannot update this, it was years ago and no one replied. I think I ended up digging for help for days and trying some things I found and finally something worked.
