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.
