[Dovecot] MacOS X and quota-plugin

Wed Nov 8 23:20:50 UTC 2006

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

Library/Logs/CrashReporter/imap.crash.log

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:
