I have no experience in setting up postfix, and thought virtualmin minght do the legwork for me. Appears not. When I try to send mail to the domain (either [email protected] [email protected] or [email protected])

I get the following message returned

This is the mail system at host dedq239.localdomain.

I'm sorry to have to inform you that your message could not
be delivered to one or more recipients. It's attached below.

For further assistance, please send mail to <postmaster>

If you do so, please include this problem report. You can
delete your own text from the attached returned message.

The mail system

<[email protected]> (expanded from <[email protected]>): User
unknown in virtual alias table

Final-Recipient: rfc822; [email protected]
Original-Recipient: rfc822;[email protected]
Action: failed
Status: 5.0.0
Diagnostic-Code: X-Postfix; User unknown in virtual alias table

How can I diagnose the problem here? It seems that the mail gets to my server but the server fails to locally deliver the message to the correct user. (This is a guess, truthfully I have no idea what is happening). I have checked my virtual alias table and it seems to be set up correctly (I can post if this would be helpful). Can anyone give me a clue as to the next step?

Thanks

My etc/postfix/virtual file is below - again myvirtualdomain is a replacement. I think this file was generated by Virtualmin and I have tried messing around with is with no success... This is the version without my changes.
