It's broke, you need to fix it. This system is an accident waiting to happen
(or a bot waiting to be owned).

Why not try a current version of dovecot. 1.0 would help a lot, and 1.1 would
be even better. 0.99.14 has been improved so much, you are just not going to
fix it easily.

You can get more current rpms of dovecot from atrpms.net, but you might have
to either try a RHEL4 version (loosely based on Core 3) or rebuild a src rpm
on a core 4 machine. That is one of the problems with running core on a
server. If you let it get too far out of service, you have more trouble
updating it.
