Hi Andrew,

*amavisd-new, which integrates SpamAssassin (with the Bayesian filter)
as well as virus scanning, as a Postfix content-filter in a large system

I think the theory is very interesting, but I have some concerns about
the practice making not just the spammers machine ineffective, but your
own as well (am I right?).  Anyway I look forward to finding out how
successful any trial is.

Daniel.
