The spammers don't often implement their own TCP/IP stacks, and therefore if their code doesn't check that it's taking an inordinately long time to write anything to the TCP socket, they'll be stuck. Wasn't there an article on slashdot a while back where a company had created a similar throttling system using asynchronous perl? I believe they claimed it worked well at stopping spam. However, if technique this isn't wide-spread, which it's not, spammers can effectively ignore it. -- Dan -- TriLUG mailing list : http://www.trilug.org/mailman/listinfo/trilug TriLUG Organizational FAQ : http://trilug.org/faq/ TriLUG Member Services FAQ : http://members.trilug.org/services_faq/
