Hello,

I have the popular email-server combination Postfix/Dovecot running here, and it is doing fine.

Virtual users, virtual domains, virtual mailboxes and virtual aliases are all there and working. Postfix/Dovecot setup is quite generic as it is described in many manuals.

However, there is one problem that I cannot solve.

Situation:
Some users deliver their mail through Postfix auth-smtp, while most use their ISP's smtp.
When the smtp-auth users send email to one of the other virtual users on the system, the mail arrives into the mailbox as expected.
But when the receiver of the mailbox has set one or more virtual-aliases, the mail is not sent to the alias address(es).
Logging says nothing about relaying denied, mail queued or postphoned, whatever.

In the "normal" situation, when smtp-auth is not used, all mail, including the mail to addresses in virt-aliases, arrives well.
I 've checked for a mailrouting problem, but there isn't: when smtp-auth users send their email directly to the addresses in the virtual-aliase.db the mail arrives as it is supposed to.

I 've been searching through the config files, but I see nothing unusual.
I hope this problem is known by anyone.

Thanks & regards, Kuba
