got some troubles with virtual domains

[Cristian Livadaru]

Hi,

now I got almost everything runing, I compiled cyrus 2.2.2Beta
I can also create mailboxes for diferent domains but when trying to send
a mail postfix tels me user unknown.
for example, lets say I have the domain foo.com and bar.com
if telnet to postfix and say
rcpt to:test at foo.com it says user unkown
BUT! if I do it like this:
rcpt to:test at foo  ( without the .com ) it works !
can someone please help me ?
