You're kidding, right? 19K dial-up ISP users (100+ virtual domains, not that the number of virtual domains matters) on a Dual 800Mhz PIII with 512MB RAM is very comfortable. Your disk I/O is the biggest issue. Add spindles. The number of users is not important. The users' proclivity to send and recieve e-mail is important. Scanning for virii/spam is important. Volume of traffic will determine your I/O subsystem. Whether you do virus/spam scanning or not will determine your CPU/RAM need. If you do virus/spam scanning, try to do the scanning on another host than your mail store. One with a big CPU and lots of RAM and an IDE disk is fine if you just want to run SpamAssassin. -- Scott Lambert KC5MLE Unix SysAdmin lambert@lambertfam.org To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-isp" in the body of the message
