Very nice stuff on anti-spam. I noted all of it.

Would you say that most spam is through SMTP relaying or through a 
legitimate SMTP server?

Some ISP's fight SPAM with the approach that all SPAM comes through 
relaying. If your SMTP server blacklists SPAM relaying SMTP servers, you 
can limit your spam inbound throughput. I didn't gather your thoughts on 
this from what you wrote. Most think that it's a losing battle and that 
the fight for SPAM happens at your front door, and that you have to 
insist upon yourself for results. What do you think?
