[Dovecot] Dovecot (IMAP) Hangs sometimes

[Mario Gomide]

Interesting.... But I used to have dovecot work with the same number of
users (up to 9,000) and with the default number of fole descriptors with no
problems... I can give it a try, though.

I can't upgrade dovecot until Red Hat releases a new version.
