No problem. You might also want to check out some
Bayes filtering software. The idea behind it is for the software to analyze an email and ascertain the probability that it's spam based on the text. In other words, if an email contains a bunch of pornographic phrases, odds are it's spam, whereas if it's talking about your aunt and uncle's vacation to Tahiti, it's probably not.
Thanks so much for your filtering suggestions - they are very much appreciated here. I have GOT to get something going on with this machine. ;-)
