I could be wrong, but I bet you could use a nice modified qmail setup in this situation. www.qmail.org - Joel ----- Original Message ----- From: Gene Holmerud To: Sent: Thursday, September 14, 2000 7:50 PM Subject: Big bucks to M$, unless someone knows sendmail... > Where I work (government) we're searching for a replacement for an > email system.
