Dear Senior Lstownrs, I do not know what is happening right now but I am receiving around 250-300 bounces a day [FISH-ECOLOGY, subs. circa 1100, traffic for the moment circa 15/20 day]. It seems "every one" is bouncing: .ZA, .AU, .NZ, .TW, .TH, .PT, .UK, .EDU, .ORG ... etc- just a mess and almost impossible to keep up with the bounces. (1) I collected the bouncing addreses and set them to nomail; did not solve anything; (2) I had to drop 20-30 subscribers; did neither solve the problem. I keep getting the bounces from other new sites. This seems impossible to get it down to cero. I would need some advice on strategies to get rid of this problem. Furthermore: What are the normal bouncing figures for other circa 1100 lists ?- Do I have to live with the, say, "10-15 sites/addresses bouncing every day + nothing-to-do about it kind of solution" ?. Friday night-Saturday=4 Megabytes of lines to read. Back to work :-) AP
