Ah, thanks.  I knew it had POP3 and IMAP proxies, but not SMTP.

I was obviously not clear enough when I said "project like this", 
though.  Python code to proxy SMTP isn't hard to come by, but I was 
talking about a Python proxy that does interesting things with the data 
provided by HELO, RCPT TO, and MAIL FROM.

In particular, I'm interested in making it very easy to experiment with 
various greylisting, tarpitting, and sender validation configurations. 
I could certainly start from Spambayes' code, or just use async, but I'm 
also interesting in judging Twisted for myself.
