Philip did not in fact have much to do with Hermes other than writing
Exim. (I think he might have had a hand in early versions of our user
administration scripts...)
Our webmail software "Prayer" was written by David Carter. It's basically
Pine for the web - it uses the UW-IMAP c-client library. We handle about
30K active / 5K concurrent users on one webmail server and it isn't
breaking a sweat.
David also did a lot of customization to Cyrus, mainly replication and
undelete. These features are part of the standard Cyrus distribution now,
and they hve been significantly improved by the guys at Fastmail.fm.
I wrote a description of our setup several years ago. The architecture is
still basically the same, though storage volumes are up by a few binary
orders of magnitude.
