Server Fault is a question and answer site for system and network administrators. It's 100% free, no registration required.

I have postfix installed on a machine named with a a virtual domain of If any email arrives at for a local user on that machine from an external SMTP server then it gets delivered locally as expected.

However if sends to using then the email is not delivered locally to user2 as expected but instead is relayed to the catch all alias for the domain

So basically local user to local user using the Postfix machine does not work. Any suggestions on how I fix or diagnose this? It has to be something really obvious.

I post my config here in case it helps:

Move the line to the end of the file. That's all.

Oh and I see it now: There should be @s in the destination addresses. So your file should look like this:

Moved "" to the end of the line and then ran postmap /etc/postfix/virtual and restarted postfix. Still has the same behaviour. Also the second column user1.mydomain is supposed to represent a local user account so the @ is not required? Suffice to say I still have the same unwanted behaviour originally described. – TheEdge Aug 24 '11 at 16:26
You have to name the user in "full-qualified" form. Or where are your virtual_mailbox_maps with these user-mailbox mappings? – mailq Aug 24 '11 at 16:38
