Nice formmail.pl probes

Nope - These systems are a mix of OSs, no formmail on any boxes in these classes.  They're just shooting the packet 
blindly when they find a HTTP response.  (I suppose though, sweep a few hundred thousand IPs, you're bound to find some 
fun sites to bounce from)
I never kicked the rule up until last night, so I wasn't aware these were flying around, manually directed, or a worm.
The goodies:
POST /cgi-bin/formmail.pl HTTP/1.1..Accept: image/gif, image/x-xbitmap, image/jpeg, image/pjpeg, */*..User-Agent: 
Microsoft URL Control - 6.00.8 Host:www.server.com..Content-Length:135..Cache-Control:no-cache...email=server () server 
com&recipient=idiot () aol com&subject=www.server.com/cgi-bin/formmail.pl&=www.server.com

Actually, it may be that your formail.pl script is being used as a
spam
relay and the bounced messages that you are seeing are from AOL
relating to invalid receipients...

 It's right behind cmd.exe on things people try to access.  There
are
 tons of spam programs that will take advantage of it.

 Not a worm, its people excited they can MAKE FUNNY FAST.  ( I would
 have said money but I'm sick of getting bounces back to the
 list/myself on stupid mail filters )

 Aol accounts are just disposable
