Hi, I had configured dovecot in a pretty standard way and had it working nicely enough with maildir quotas (no tests done apart for reaching the quota and looking at mails coming back). Still I wanted to have the quota and the actual quota usage displayed in postfixadmin (3.5) but I think I messed with something. Now I can connect to the mailbox, send mail, receive mail, see the quota usage in postfixadmin but:

• thunderbird: can create a subfolder if i do so by hand from the client. But if I try sending a mail i get a [TRYCREATE] mailbox error as it seems that thunderbird can't create the Sent box anymore by its own;
• thunderbird: when i delete mail, it goes in the trash folder. I try then to delete it from there. In thunderbird indeed I see no mail anymore but the quota level remain the same. Then I try to browser the mail directory and... yep, all the messages are still there! How come?

This is the output of dovecot -n and the relevant sql configuration :
