Default value changes in Cyrus 3

[Bron Gondwana]

Yes, if you change either it will force a re-download of messages and
resync of mailbox listing.
I would recommend setting it to the old values if you upgrade an
existing server.  You can also do something like we did at FastMail -
set up a new hostname with the new defaults using per-service imapd.conf
options, and recommend that  users use the new hostname when setting up
new clients.  That way you don't break things for existing users.
The reason for new defaults in a major version change is to allow new
sites to have sane defaults for the future.
Bron.
