dovecot - Oct 2010 - Problem with quota and mdbox and quota warning

Hi again,

I just recognized that my dovecot forgets the quota for a mailbox.
This is what the maildirsize looks like:

1 read mail present, 1 new/unread mail
2097152S
0 0
909936 1

and later, with 2 read mails:
2097152S
0 0

There are no errors logged.


Moreover, my quota warning script doesn?t work because dovecot doesn?t
recognize my specified folder. I specified 
/usr/local/etc/dovecot/quota-warning.sh but the log shows that dovecot 
looks somewhere else:

Error: quota: connect(/usr/local/var/run/dovecot/quota-warning) failed:

mdbox doesn't work with Maildir++ quota, you need to use dict quota with
e.g. file backend.

You need to give enough permissions for that.

You should upgrade to v2.0.6 in any case. It'll also give you better error
messages.

This behaviour is very weird.
My script is /usr/local/etc/dovecot/quota-warning.sh and after reloading
dovecot generates the file /usr/local/var/run/dovecot/quota-warning
with wrong permissions?

So everytime I have or want to restart dovecot, I have to re-set the
rights for this file?

No. Did you see this part of my mail:

Set the permissions as you want in the unix_listener.
