Hi Timo,
Thanks for the info, the version of dovecot installed is
root@gwvmdmzmail01:~# dovecot --version 1.2.15 root@gwvmdmzmail01:~#
Whats the safest way, without loosing data or breaking the mail system is recommended to upgrade dovecot to version 2.2.5?
many thanks
~Jay

Since I already got 3 private mails about this, here's the same reply for everyone (actually updated, now that I looked at the code):
This was a v2.2-only bug. And it isn't really a DoS.. It only caused the one pop3 process to crash in assert, which was handling only the connection that had already disconnected. (Unless you were running a non-recommended configuration with multiple clients per process.) So the only problem it caused was that Dovecot logged an assert error and maybe wrote a core dump.
