Hi!
I'm playing with a postfix + dovecot + mysql test setup, and noticed
something strange. It seems that despite the "username changed" line,
auth returns the original username:

I've checked this with the LMTP service (i know, normally it wouldn't
get mail addresses) and it produces the same:

Passdb works as it should. IMAP test:

Can someone tell what should i do to make this work? Or any idea i could try?
It would help if Postfix would be able to run Virtual before the
policy check, but thats a problem for the postfix list. :)
Thanks!
Peter
