Yes, PAM can be used. Authentication is done by SASLv2 thus the
saslauthd. The default configuration auths against the system's shadow
file which is with default PAM setup the same as using saslauthd -> PAM.

Ok, then switch the IMAP server as soon as possible. dovecot could be a
valid candidate too. It has either capability to use mbox format which
would allow you to keep the current mail in the mboxes - along with
indexing it is fast too - and it can handle Maildir too. dovecot comes
with FC2 and FC3 as well and is easier to setup.

The usual marketing games ;) Give a marketing guy a buzzword and he will
claim you can fly to Mars using product XY.

Maybe a good strategy is to write down your own a list of needs and
nice-to-have features. Then compare that list with the feature lists of
the products. Each has pros and cons. A general answer is hard to give
if not knowing all details about the specific environment, current needs
and future plans.
