I read your prior post - but my response is still "Why?"

If sendmail has already determined that the recipient be rejected, what is the purpose of calling an additional FILTER to make a determination?

What you want is LOGGING, not filtering.  The milter interface for filtering is NOT the place to do that.  Logging is easy.  Append to the M4 code for check_recipient a map call to syslog with the appropriate information and reason.  [Then, read the logs.]

This is not a MimeDefang problem.
