yes.

nope, postfix.

I'd show you diffs, but CVS is busted for me (apparently the hostname changed 
from cvs.mailman.sourceforge.net to just cvs.sourceforge.net, and I'm not good 
enough with CVS to know if I can just go change that in all the Root files and 
expect it to work.)

Pretty much all I did was add in a new named arg "mail_options=["XVERP"]" to the 
call to conn.sendmail() in Handlers/SMTPDirect.py (because that's how you get 
Postfix to add the VERP info, just send it that option on the connection).
