By far, IMHO, the best is cyrus-imapd ... it was originally developed by Carnegie-Mellon University to handle their on campus email, and grew quickly out of that ... If I recall your environment at all, one nice feature of it is that it supports something called MURDER, which, effectively, is a way of having your mailboxes literally spread out over multiple backend servers ... all the mail comes in through ServerA, but, as an example, mailboxes a-m get stored on ServerB, and n-z go to ServerC ... They've also just recently added a replication ability, so that you can have backup servers ... ServerD is a backup of ServerB, ServerE is a backup of ServerC ... The thing is, it would most likely eliminate, or greatly reduce, your NFS requirements ... ---- Marc G.
