from the documentation page
http://www.postfix.org/postconf.5.html#virtual_mailbox_maps

virtual_mailbox_maps (default: empty)

In a lookup table, specify a left-hand side of "@domain.tld" to match
any user in the specified domain that does not have a specific
"u...@domain.tld" entry.

The remainder of this text is specific to the virtual(8)
 delivery agent. It does not
apply when mail is delivered with a different mail delivery program.

What you are probably looking for is virtual_alias_maps

So I'm trying to do a virtual domain+virtual users setup with Dovecot 
where
I'd have several virtual domains and several users. Each user is 
supposed to
be authenticated via the simple username both for SMTP and IMAP, not a 
full
email address and each will have several email aliases on different 
domains.
Pretty simple so far. However, I've set up the virtual_transport to be 
lmtp
and that transport relays the entire recipient's email address to 
Dovecot.


main.cf:

virtual_transport = lmtp:unix:private/dovecot-lmtp
virtual_mailbox_domains = aqq.is
virtual_mailbox_maps = hash:/usr/local/etc/postfix/virtualmailboxes

virtualmailboxes:
t...@aqq.is testmail
te...@aqq.istestmail

And in the mail log:

dovecot: lmtp(20405): Connect from local
dovecot: auth-worker(20407): passwd(t...@aqq.is): unknown user



There's so much missing information here that it is impossible to know 
what's happening.


See http://www.postfix.org/DEBUG_README.html#mail for suggestions of 
what information to provide to make it possible for others here to 
assist you. Most important: the output of 'postconf -n' and all of the 
possibly relevant log lines, intact.
