Did you check what commands Thunderbird sends? Use e.g. rawlog
(http://dovecot.org/bugreport.html). I don't think snarf plugin should
cause this, and in general I can't think of a bug in Dovecot that would
cause this.

I'm guessing what happens is:

C: 1 APPEND Drafts {...}
S: 1 NO [TRYCREATE] Mailbox doesn't exist.
C: 2 CREATE Drafts
S: 2 OK

Maybe at that point Thunderbird doesn't bother to try again anymore.

Right. If you want .imap_mail/inbox to be used always, either change the
mbox snarf code (remove stat(mstorage->snarf_inbox_path, &st) check) or
make sure to create the file when creating new users.

Doesn't Dovecot use /var/mail/$user then as the INBOX if
the .imap_mail/inbox doesn't exist?
