Thanks.

Milter is obviously more generic, but it
1. is a rather complicated protocol, ergo "implementation overhead", and
2. requires that all message data is passed over the socket.

Current approach allows one to analyze the message "in place" (if you
use mmap()) and potentially minimize transfer of data between disk and
memory.  I think that both interfaces may and should peacefully coexist.
