mailfront on IPv6 ?

I've been using mailfront since 1.11.  For reasons that are more political 
than technical, I want to set up a mail server on IPv6 and see what shows 
up.  Does anyone have experience using mailfront on v6 connections?

There's an IPv6 set of patches to tcpserver from about 2002 that seems to 
work OK, and a TCP session is the same on v6 as it is on v4, but the 
environment variables are different.

Also, I have some additional modules that people are welcome to if you 
want.  There's one for DCC, the distributed bulk counting package, one for 
spamassassin that's a little cleverer than Bruce's, one that logs the mail 
envelopes in a mysql database, and one that does greylisting, via UDP 
queries to a small daemon written in perl.

I slightly modified the CVM plugin to remember the controlling username 
after a qmail lookup, and use that in the dcc and spamassassin plugins so 
it uses the appropriate per-user config.
