Hello!

I'm having this strange problem with postfix and virtual e-mail
addresses. Everything sent to "real" mailboxes gets thru perfectly.
But problem is with virtual email aliases.
Seems like smtpd is able to "resolve" the address where mail sent to
alias should go to, but virtual is unable to figure it out... postmap
-q is able to resolve the alias aswell, this leaves me puzzled. Any
ideas?

I tried to include everything useful here:

Mail sent to "testausxox.fi" ... from /var/log/mail.info:

opposed to sending to invalid e-mail address /var/log/mail.info:

Aug 29 18:05:30 gorilla postfix/smtpd[30124]: connect from flexo.
4tune.fi[212.83.122.100]

Aug 29 18:05:30 gorilla postfix/smtpd[30124]: disconnect from flexo.
4tune.fi[212.83.122.100]

However,
joonagorilla:~$ sudo postmap -q testausxox.fi proxy:mysql:/etc/
postfix/mysql_virtual_alias_maps.cf
joonakuori.org
joonagorilla:~$ echo $?
0

Mailboxes (while virtual aswell) work fine tho:
