Package: dovecot-common
Using : Debian 6 , Postfix + MySQL + Dovecot IMAP, POP3, LDA
At postfix main.cf :
virtual_transport = dovecot
At postfix master.cf :
dovecot unix - n n - - pipe
flags=DRhu user=client1:client1 argv=/usr/lib/dovecot/deliver -f
${sender} -d ${user}@${nexthop} -n -m ${extension}
dovecot limit :
plugin {
quota = maildir:User quota
quota_rule = storage=50M:messages=1000
quota_exceeded_message = Quota exceeded, please go to
http://www.example.com/over_quota_help for instructions on how to fix this.
}
dovecot sql :
user_query = SELECT CONCAT(`domain`,'/',`login`) AS maildir, 1001 AS
uid, 1001 AS gid, CONCAT('*:bytes=',quota*1024*1024) as quota_rule FROM
postfix_mailboxes JOIN postfix_virtual_domains ON domain_id =
postfix_virtual_domains.id WHERE domain = '%d' AND login = '%n'
mysql> SELECT CONCAT(`domain`,'/',`login`) AS maildir, 1001 AS uid, 1001

postfix_virtual_domains.id WHERE domain = 'service.local' AND login =
'test2';

As you see, quota limit - 1mb . When I try to check my quota and send
mail with attach large, then 1mb ( for example - 2mb ) I have error at
my logs :
Feb 25 14:52:04 kolyav postfix/pipe[16143]: 4FD3510A23A5:
to=<test2@service.local>, relay=dovecot, delay=3.7, delays=3.2/0/0/0.54,
dsn=5.3.0, status=bounced (Command died with signal 11:
"/usr/lib/dovecot/deliver")
Okay, I try to debug it with dbg, because signal 11 - it's crash. I
change my dovecot lda at postfix master.cf :
dovecot unix - n n - - pipe
flags=DRhu user=client1:client1 argv=/usr/lib/dovecot/gdbhelper
/tmp/deliver.sh -d ${recipient}
cat /tmp/deliver.sh
#!/bin/sh
sleep 1
exec /usr/lib/dovecot/deliver $*
and try one more time and have debug information :

In this debug log I see seg fault :

this errors goes me to this patch -
http://hg.dovecot.org/dovecot-2.0/rev/89936539e3b8
but I can't see dovecot2 at any Debian repository.
