NGMP: Inbound SMTP wiki

The subject of how to handle incoming SMTP sessions is a pretty sticky issue. 
I have been thinking about it alot but I want to have more input on the 
subject. NGMP needs to allow incoming SMTP to remain backwards compatible, 
but I think it also needs to provide some built-in spam protections 
(otherwise we lose the nice improvements of the IM2000 concept until/unless 
NGMP becomes widespread enough to start closing port 25 -- not likely in the 
forseeable future, IMHO). I have set up a wiki page with some musings of my 
own on it, but I would love to have those musings ripped to shreds and 
eventually converted into some workable ideas. :) So, have at it:
