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:

Apr 17 09:30:35 imap21 dovecot: auth-worker(27730): Debug: sql(ppp@example.net,127.0.0.1): SELECT at.userid AS user, at.home AS home, at.uid AS uid, at.gid AS gid, concat('*:storage=', at.quotabytes, 'b:messages=', at.quotamessages) AS quota_rule FROM auth at INNER JOIN mailaddr mt ON at.userid = mt.userid WHERE mt.mailaddress = 'ppp@example.net' OR at.userid = 'ppp@example.net' Apr 17 09:30:35 imap21 dovecot: auth-worker(27730): Debug: sql(ppp@example.net,127.0.0.1): username changed ppp@example.net -> uppp Apr 17 09:30:35 imap21 dovecot: auth: Debug: userdb out: USER#0111#011ppp@example.net#011home=/home/ppp#011uid=500#011gid=500#011quota_rule=*:storage=3100b:messages=1024 Apr 17 09:30:35 imap21 dovecot: lmtp(27728): Debug: auth input: ppp@example.net home=/home/ppp uid=500 gid=500 quota_rule=*:storage=3100b:messages=1024 Apr 17 09:30:35 imap21 dovecot: lmtp(27728): Debug: Added userdb setting: plugin/quota_rule=*:storage=3100b:messages=1024 Apr 17 09:30:35 imap21 dovecot: lmtp(27728, ppp@example.net): Debug: Effective uid=500, gid=500, home=/home/ppp

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
