I have virtualmin and settings on virtualhost: mailname and hosts mydomain.com

I have all my emails accounts on gmail e.g. support@mydomain.com

However when sending emails in Joomla (PHP Mail setting) I have in mail.log

 8BB689FE64: to=<support@mydomain.com>, relay=local, delay=0.05, delays=0.03/0/0/0.01, dsn=5.1.1, status=bounced (unknown user: "support")

It treats mydomain.com as local, this domain is on gmail.

When sending to other than mydomain.com it send fine.

Try this:

1) Have a look in /etc/postfix for any mention of mydomain.com

2) Add the following line to /etc/postfix/transport

mydomain.com smtp:SERVER

where SERVER is the correct mail server (MX record) for your domain at gmail.com. You could try putting gmail.com, but I'm not sure. Have a look for the right answer using "host mydomain.com" or dig.

Then run:

postmap /etc/postfix/transport

Restart postfix and Bob's your uncle. Hopefully...

I had changed mydomain.com in main.cf but did not help as domain A points to my server –  miojamo Sep 20 '11 at 18:21
Did the transport stuff not help? –  ed. Sep 20 '11 at 18:26
nope still relay=local instead to google apps –  miojamo Sep 20 '11 at 18:39
OP fixed the issue: "I fixed the issue by not setting the mydestination param in main.cf." –  Jeff Atwood Sep 29 '11 at 9:55
don't specified the domain mydestination or virtual_mailbox_domains, because your domain is in an external mail server –  c4f4t0r Aug 23 '14 at 15:32
