Actually it's correct if you're using sendmail.  The sendmail MTA will 
detect that you're running an older libmilter and downgrade its use of the 
protocol accordingly (and vice-versa).

Apparently either postfix makes some assertions about what version of 
milter will be used by filters, or the version it's using is configurable 
and defaults to the newest stuff with no automatic back-compatibility.  In 
either case, that's something postfix should document.

If someone wants to provide some appropriate postfix-specific text for the 
README, I'd be happy to include it.
