Yes I was being mostly facetious. But as others pointed out- Micro$not is as much to blame for the spam problem as Road Runner and CommieCast with their extremely shoddy software. Open proxies, worms, relays, spyware ad nauseum.
<late-night-humor>I was amused at this and decided to look real quick.. OpenBSD's pf can block on OS fingerprints.. effectively doing exactly what you are kidding about (at least I'd hope so.. well, maybe) even in the man page example they put:# Do not allow Windows 9x SMTP connections since they are typically # a viral worm. Alternately we could limit these OSes to 1 connection each. block in on $ext_if proto tcp from any os {"Windows 95", "Windows 98"} \ to any port smtp The OS fingerprint list they have is rather extensive.. </late-night-humor> :) Mike Jezierski - BOFH wrote: {sniped}the damned operating system Micro$haft. If there was a blackhole list to block all Windows lUsers it would be more effective - granted that would also reduce email down to about 10% of the computing population.No zombies on my Macintosh regards.....
