Apologies to those who didn't get the Monty Python reference ( there is no rule 6, after all! ), I'll take the general census as an ok, and hope this isn't too off-list. I'm working for a company down here in Christchurch who are developing a new tool aimed at catching email spam. Much simplified, it uses linear regression techniques to create a signature of the email involved, and then performs a fuzzy match on that sig against databases held on our servers ( via a local cache to improve performance ). We reckon we've got it to be pretty indestructible ( and with a pretty small footprint ), but we need to test it further. Are there any ISP's out there who could help us out by a) trialling it ( our testing up to now has been as a milter under sendmail/postfix on linux ), and/or b) sending us loads of spam to stress our backend processes?? If so, could they contact me offlist? Cheers and thanks, Steve
