Actually, if you run *massively* large lists, it's even MORE important to clean things up. 2% bad addresses on a 200 person mailing list means 1 post in, one mail item out, and then 4 bounces back to Listserv. On the other hand, if you have 2% bad on a 50,000 person mailing list, that's *1,000* bounce messages that you'll be receiving. I have a 70K recipient list - the performance issue in postings to it isn't delivering 70K messages. Sendmail is quite good at handling those in paralell. It's catching the bounces afterwards - all those have to thread through lsv_amin and the main lsv process single-threaded. /Valdis
