While this is definately true in HTTP (as sensitive information travesrses
the network otherwise unencrypted), it is no where near as important in
IMAP, unless you are concerned about people knowing what mailboxes you
select (or if you use a mailbox that only gets APPENDed to).
In almost every case, all of the information available in Cyrus has
already crossed the network unencrypted, be it via SMTP between sites or
via NNTP from a feeder peer. So, the contents of the messages have
already been exposed, so the *content* isn't secure anyway.
The only argument I currently completely understand for an IP-only based
setup is that of sites that need to distinguish ANONYMOUS users between
domains (and prehaps that is good enough).
