Re: [Asrg] 6. Email Path Verification (hashcash benchmarks)

During one of the latest e-mail viruses, one of my clients started labeling all of the reproductive messages as spam. Within a few training sessions, the virus problem went away because it was all placed in the dumpster. Personally, I never would have thought of doing that but I have a clever client.

I did the same with SpamAssassin when Sobig.F started hitting me with hundreds per day (bounces and infections alike). I manually set the MICROSOFT_EXECUTABLE score to 10.0 (the default score is only 0.3) and set up Procmail to dump messages above 8.0. I'm pretty sure that dealt with over 99% of the problem.

I personally think that nearly all ISPs, especially those with a large proportion of newbies, should delete directly-executable attachments without question.
