You could do that on any machine bigger than 500Mhz with 256MB of memory without any problems. Disk should be how ever much you think you'll need. On average, each user will eat up about 5MB of disk space with POP accounts, and somewhat more with IMAP. If you want to add site-wide SpamAssassin spam-filtering, you'll want a 1Ghz machine at least, preferably with multiple processors, or you'll need to offload the spam-filtering to a seperate box or boxes. -- Ted Cabeen http://www.pobox.com/~secabeen ted@impulse.net Check Website or Keyserver for PGP/GPG Key BA0349D2 secabeen@pobox.com "I have taken all knowledge to be my province." -F.
