Hello,
I recently had the problem, that an index was corrupt. Thus, messages
haven't been listed (talking about POP3), but still remained in the
filesystem. As there is no SEARCH-command in POP3, dovecot didn't notice
that the index is corrupt and didn't rebuild it. The problem is, that a
user can't delete messages through POP3 which aren't listed by dovecot.
If the maildir size increases, the arrival of new messages will be
blocked because the mailbox is full. And the user has no chance to
delete it.
Regards
Marten
