+1  Cyrus having its own identity management has been a big plus; the
server as kind of a service-sandbox.

Same here.  I migrated from UW l-o-n-g ago as UW so desperately
struggled with large mailboxes.

Agree [but, honestly, I've never understood the cyrus-is-complicated
bit].  Cyrus is self-contained, which makes it much easier to
administer.
