I am getting a bounce from a former subscriber (an out of office message) and it keeps coming. I've deleted my LSMTP spool files and made sure his address doesn't appear in any file anywhere in either the Listserv or LSMTP directories. Yet ever 2 seconds or so I get another message back from this bozo. Each time a message comes into Listserv it says its sending him an informational response. I've removed him from the list, I've put him in my Filter= line, what more can I do to stop this Denial of Service attack from hell????? I cannot filter on the IP address easily so I need another alternative. Cheers, Russ Cooper - NTBugtraq Moderator owner of the NTBugtraq mailing list - http://www.ntbugtraq.com
