I simply stopped all relaying whatsoever, I'm behind a slow modem and to use me is pretty ridiculous unless you're up to something shady. I thank all you guys who showed me what to do! Could I press one step further, and ask how I get procmail wired in, so that I can use automated filtering based upon some net database like the realtime blackhole list? I use Pine as my MTA, and I don't want to change that, but I'm not sure how to shoehorn procmail into that. > ----------------------------+----------------------------------------------- Chuck Robey | Interests include any kind of voice or data chuckr@picnic.mat.net | communications topic, C programming, and Unix. 213 Lakeside Drive Apt T-1 | Greenbelt, MD 20770 | I run picnic and jaunt, both FreeBSD-current.
