Here's my reinforcement for doing nothing: a year or two back, I somehow got added to some mailing list belonging to a Florida Hospital (as useless a thing for somebody to do as can be imagined seeing I don't live in the USA, let alone Florida, so probably a spammer infected their mailing list or stole their list address). As usual, I added that address to my personal blacklist: problem solved. However, I was feeling helpful that day, so also emailed their 'abuse' address to let them know they had a problem. Didn't bounce, so they must have got it. Did they do anything? Apparently not. I still get their spam, but at least my system bins it automatically. Martin
