As an example, I (still) have a 66MHz 486 with 48MB RAM and a single 2GB SCSI drive handling over 300 users with sendmail and cyrus-imapd. Focus on reliability foremost, so mirror those two SCSI drives you have. The Proliant 1850R doesn't offer the ability to use redundant memory, but it at least does ECC. You'll also have an extra processor already there if one happens to go south, and you would never notice it was gone. > Software: > postfix, courier-imap, bind Consider cyrus-imapd2 or cyrus-imapd22 instead of courier-imap. Very reliable, very fast, and offers you the ability to create a "black box" mail appliance that does not require the use of local user accounts, if you wish to go that route. -- Chris Dillon - cdillon(at)wolves.k12.mo.us FreeBSD: The fastest and most stable server OS on the planet - Available for IA32, IA64, PC98, Alpha, and UltraSPARC architectures - x86-64, PowerPC, ARM, MIPS, and S/390 under development - http://www.freebsd.org No trees were harmed in the composition of this message, although some electrons were mildly inconvenienced.
