Could be.

Yes, see the other messages here with "poodle" in the subject. I laid
out a plan of action how this will be done. But there are certain
complexities to this due to our version of Dovecot being to old. Once
that's solved I'll build a set of updates that disables SSLv3 for all
services.

As for FTP accepting connections on port 990: Filezilla, define server,
select port 990, choose "explicit". The connection works. I'd rather not
take functionality away if it *just* works.
