Hi all,

I've installed dovecot 1.0 rc12 on a MacOS X client system with only
a handful of users – all virtual – and would like to enable quotas.
I've tried searching the wiki for information on how to do this, but
haven't been able to find anything – which is why I turn to the list
in hope there's someone out there who can point me in the right
direction.

I've compiled dovecot without any other authentication than sql and
pam, and have enabled ssl, pop3 and dovecot lda (for use with postfix
when I get around to it). The installation went smoothly, and dovecot
is working great without quota-support. However, when I enable quota- support, the imap child-process crashes. Here's a few lines from the
log, slightly altered to protect user-identities:

Nov 8 23:05:09 SD-Server dovecot: imap-login: Login:
user=<imapuser>, method=PLAIN, rip=192.168.2.10, lip=192.168.2.2, TLS Nov 8 23:05:09 SD-Server dovecot: child 22662 (imap) killed with

This is what I have done in dovecot.conf to enable quota:

protocol imap { mail_plugins = quota imap_quota mail_plugin_dir = /usr/local/lib/dovecot/imap }

plugin { #quota = dict:storage=10240 #quota = dirsize:storage=10240 #quota = maildir:storage=10240 #quota = maildir:storage=10240 mysql:/usr/local/etc/dovecot-sql.conf #quota = fs:storage=10240 #quota = fs }

As you might guess from the lines under "plugin", I've tried a lot of
different combinations. If I enable ANY of the above lines under
plugin, the child-processes die upon login. When all have been
commented out, there's no more crashing – until I try to see how much
space is available, then it crashes again. I've tried adding an extra
"quota" field to my mysql userdb to handle quotas, but with the same
result.

mysql-query looks like this (as described in the wiki):

user_query = SELECT home, uid, gid, 'dirsize:storage=' || quota_kb AS
quota FROM users WHERE userid = '%u'

As with the settings in dovecot.conf, Ive tried various combinations
of dict, dirsize and so on, but without any luck.

This is what the entries in my crashdump file looks like:
