In the last two weeks or so I got spammed from SPRY/Compuserve at lest half-a-dozen times. You don't seem to be blocking them, do you?
No. But I do block the /32's used by spammers to relay mail through Prodigy. I have not personally been spammed via Compuserve recently, and moreover they have been very active in getting their Sendmail upgraded to make this kind of unintended relay service stop. I don't have a hair trigger on this gun -- it takes quite a while for me to decide that someone can't/won't come around on their own. And when I block things I do it with as long a prefix as possible, since I am not trying to penalize anybody and I want all "cooperative" portions of the net to reach me. Thanks for asking, even though your implicatory tone is very damaging to you.
