Once you've used cyrus, you'd never go back to uw-imap or dovecot
Each e-mail is stored as a separate file, not a nasty single mbox file
that gets large.
Note that the competitors can use maildir, so this isn't a Cyrus-only
feature.

actually, cyrus doesn't use maildir but it's not altogether that
different in concept...but of course, there really is no standard
definition for maildir but what was implemented by vpopmail seems have
been adopted by courier and dovecot

vpopmail does not implement maildir. Maildir is a DJB invention and
vpopmail just automates certain aspects of creating a mailstore based on
maildir. courier and dovecot choose to support this open format along
with other mtas besides qmail, where it was first implemented.
But AFAIK this comes at a storage penalty: Many small files will waste
space approximately equal to half the storage allocation unit times the
number of files. Or is there a way to mitigate this on ext3? (I don't want
to go to Reiser.)

Reiser seems to have lost most of it's lustre but there are of course
other types of storage.
Ah, kernel politics and whatever...nice that such things get in the way
of technology. Look at zfs (okay, not the best whatever but the thing is
sweet to use) and they broke all the 'rules'. We could have had a great
filesystem plus compression and a whole lot more were it not for kernel
politics. Then there was the recent CK thing.
