So far today, my server has rejected over 18,000 messages to unknown users (and only delivered 1,400 legitimate messages). Recently we've been averaging about 60,000 per day. I had to redesign our mail system so I wouldn't have to virus scan all that junk. I had three servers doing nothing but virus scanning and they couldn't keep up. Now, one server with Courier, Amavis, ClamAV, and SpamAssassin handles it easily. Bowie
