dovecot - Jul 2008 - dovecot-imap displays empty domainalias mailboxen

Hi folks,
I'm using dovecot 1.0.13 as the IMAPS frontend for a vpopmail/qmail
virtual domain setup. Dovecot is set up as follows:
passdb vpopmail{
}
userdb vpopmail{
}

I've added a domain alias for the main domain with vaddaliasdomain and
email to post at aliasdomain is delivered to post at maindomain and can be
checked with pop.

However, when I try to check IMAP through the account post at aliasdomain
I am confronted with an empty mailbox. If I log in using
post at maindomain I get the expected contents.

Why can't my users log in using user at aliasdomain to check their emails?

Regards,
 Kacper Wysocki
