I see what you're getting at.. I've never looked at it from that stand  
point before so it didn't make sense to me. I use mailman primarily  
for internal communication for my company, the ability to send a file  
to art at mydomain.com and it goes to who ever is in the art department  
that day has been great!

I completely agree... Greylisting isn't the best way to use it. I  
should say though that I might be in a different configuration then  
you... Most of the people who e-mail my domain are our customers and  
have their own domain. So I can white list all of our customers since  
the chance of spam is very low from their company mail servers.  
Greylisting also helped me get my feet wet with spam related issues  
since I wasn't ready to start blocking based on content.

But now we get too much spam making it around the greylisting so I  
need to get back into the fight against spam! :)
