Have a look at the Hermes mail system at cam.Ac.uk, built buy among people Philip Hazel of exam fame
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. http://www-uxsup.csx.cam.ac.uk/~fanf2/hermes/doc/talks/2004-02-ukuug/ Tony. -- f.anthony.n.finch <dot@dotat.at> http://dotat.at/ East Malin, East Hebrides: Variable 4, becoming westerly then southwesterly 5 to 7.
