Postfix version = 2.1.5
mydestination = $myhostname, $mydomain, $transport_maps
transport_maps = mysql:/etc/postfix/mysql_transport_maps.cf
unknown_local_recipient_reject_code = 550
relay_recipient_maps = $virtual_mailbox_maps
failback_transport = /ust/bin/maildrop
virtual_alias_maps = mysql:/etc/postfix/mysql_virtual_alias_maps.cf
virtual_gid_maps = static:108

>Why are your virtual mailbox users in "relay_domains"?
My virtual mailbox users aren't in "relay_domains". My relay control are
taken by $transport_maps in "mydestination" line. Like you can see above..
If the final destination domain is listed on mysql_transport_maps.cf, then
the relay will be accepted. If the domain isn't there, they will get a
"relay access denied" ..
Like I said before, my postfix setup don't have problems.. The only problem
that a had was to reject unknown mail users..
my environment: postfix+mysql+clamav+maildrop
When an outbound smtp server tried to send a message to unknown users,
maildrop replies with the error: Invalid user specified.
And a bounce message was sent back to sender.. without success, because
almost the time the MX destination does not exist.. sure. It is a SPAMMER..
I found on some forums that the problem is because the use of maildrop and
failback_transport = /ust/bin/maildrop
When I put the option: relay_recipient_maps = $virtual_mailbox_maps
Everything works fine..
Now, when a smtp tries to send a message to an unknown user, my postfix
replies whit this:
Recipient address rejected: User unknown in local recipient table.
I don't really now if is the best way to solve the problem.. but its works
fine to me, and the most important is that a solve my problem..
Sorry about my English, I'm trying to get better.
Best Regards,
Danilo.

This is not an explanation. What version of Postfix are you using.
What is the complete set of explicit main.cf settings ("postconf -n"
output). Why are your virtual mailbox users in "relay_domains"? It
looks like you have failed to set "virtual_mailbox_domains" correctly,
and are avoiding the real problem by enabling relay recipient validation.
