Heck, that's *nothing*. Forget 'big heavy servers', if you're on a significant number of FreeBSD mailing lists you're getting close to 10K/month, and that's per/user. 700K/month is chicken feed, and I'm sure my 486/66 with FreeBSD could handle with w/out even breaking a sweat. Using a nice round 1 million email number a month gives you approximately 24/minute, which means that youre server is probably more I/O bound than CPU bound. Get a good fast disk on the box and have at it. > So I'm interested in some stats from some of the larger mail servers > running FreeBSD, and particularly freebsd.org itself, in terms of > system size, MTA and version, and the mail load being handled.
