dovecot - Jun 2011 - quota_rule beeing ignored and set to system soft! quota

Hi,

originating from the same Problem Edgar Fu? described here [1]  about
"Zero-sized Maildir files and index corruption on over-quota" i setup
quota = fs:user quotas with a quota_rule set to 1.5G to prevent getting
those zero sized mail files. What happens now is that when the user is
over system soft quota (1G) mails stop beeing delivered.

Jun 16 19:05:45 mail dovecot: deliver(elont1):
msgid=<20110616185545.05ab0f56 at x201t>: save failed to INBOX: Quota
exceeded (mailbox for user is full)

This is bad as users get notified per mail by a script about beeing over
quota (this mail is now beeing deferred). If i don't set a
quota_rule i still get 0byte files (quota is ignored). If i set a higher
than system quota quota_rule it still uses the system soft quota.

I have a seconary mailserver which already uses dovecot 2.x but i can't
test the feature there as it's running inside a jail and thus has no
access to quota. I would like to keep this machine on 1.2.16 for now.

dovecot -n output is below.

thanks,
Leon
