One of the two mail servers I use is an ancient qmail setup that dates from around 1998, and spam filtering is not its strong point. So spamassassin catches about 40 a day, and I feed about that many to sa-learn manually. Jim tells me that qmail's filters do stop around 20,000 a day according to its logs. Also, of the 100 incoming ports, a mail will time out and be bounced by the sender because the spammers will open a port and forget to close it, so its out of incoming ports about 50% of the day. A whole new machine has been built, around sendmail I think, with quite a bit more iron, but he has a vacation week coming up and is not about to make the changeover and leave for a week.
