Good POP3 Server for Huge Mailboxes?

brainchill asks: "I've got about 10,000 users split between a couple of quad 550 xeon machines. The machines have 2GB of ram. The problem is that the UW POP3 server takes a huge hit in both cpu and memory utilization when a 40+MB mail spool is requested via POP3. Sometimes it's bad enough to drag the monster boxes to their knees. What other POP3 daemons do you guys have experience with and how do they perform with large mailboxes"

http://www.dbmail.org/ I was looking thru their site, havent actually used it but it sounds like it might reduce the load on you're servers massively. tho i'd want to use postgres and not mysql for the back end.

Your problem is caused partly by hardware?

Could your problem be caused partly by hardware? Hevanet.com, the best ISP in Portland, Oregon, USA, uses a special SCSI system run with a special version of NetBSD supplied by a company in Arizona.

Retrieval of mail stresses the filesystem; Hevanet's system is a combination of OS and hardware meant to take the load.

If a mail server is "trashed" or "crashes" (I've also seen complained about) simply because it was sent a large email, then the server is, frankly, buggy. Instead of trying to run with a flaky server and put policy requirements on users to work around the problems in the server, use a non-broken server.
