Mailbox locking issue?
...ock = fcntl, dotlock The problem is the following. A user uses fetchmail via an ssh tunnel to download mail via pop3 every 5 minutes. This normally works fine. perhaps once a week or so, maillog shows that Postfix delivers a message while fetchmail is retrieving. Here is one such.

Assertion error in Dovecot 2.2.6

Dovecot under brute force attack - nice attacker
Hi List, optimizing the configuration on one of our servers (which was hit by a brute force attack on dovecot) showed an odd behavior. Dovecot Version 1.0.7 (CentOS 5.2) The short story: On one of our servers an attacker did a brute force attack on dovecot (pop3). Since the attacker closed and reopened the connection after every user/password combination the logs showed many lines like
