i will agree with tikiri, et al. - although my personal experience is that you need more than a p1 to act as your external mail relay. email is heavily disk i/o dependent, so you need decent disk speed, but i have no hard numbers/speeds, so ymmv if you are needing an external mail relay for a small-midsize office, i would recommend openbsd and postfix, for larger deployments i like freebsd/postfix (my personal biases, use whatever *nix/smtp server you are most comfortable with)...if you do decide to look at openbsd/postfix, here is a good howto: http://lawmonkey.org/anti-spam.html - there are other howtos, but i am partial to this one ;) cheers /joshua [cut] __________________________________ Do you Yahoo!?
