Ok, found the problem and fixed it.

Two things had to be done:

------------------------------------------------
master.cnf

service dict {
 extra_groups = vmail
 unix_listener dict {
   group = vmail
   mode = 0660
 }
}
------------------------------------------------

After restart I got another problem which I fixed with this patch (Thanks Andrey!)

       sql_result_unref(result);

I also wrote Timo an email regarding this problem. Hope he fixes it soon.

Hi,

I have a problem when setting up the quota dict plugin. I get this error in my logfile when trying to store a draft (APPEND):

The file is there:

What is going on there, how can I fix this?
