As long as this isn't the place to discuss these points and I don't believe
we can't agree on it, I stop discussion.

But I can point you some links (found with google) :

* A description of milter protocol. Not up to date, but near valid.


* libmilter/engine.c (from sendmail distribution), is the file with all code
   implementing the libmilter protocol (around 1700 lines long) on libmilter

* sendmail/milter.c (from sendmail distribution) is the file implementing
   libmilter protocol on sendmail side.

* you'll also find inside postfix, the code used by postfix to implement
   the protocol, on postfix side

* Open software are very interesting as they allow you to get info on how
   to use them and improve them. Other sendmail/libmilter and posftix, you
   can find interesting information on how to create the libmilter side code
   to perform as you think it shall be done. Other interesting pointers are
   (people doing or had done that)
