No way? I really like the way opensmtpd is configured and I would hate to move back to postfix but this is really critical

Any ideas or hints?

On sendmail, I use the milter API.  The filter API on opensmtpd might
be able to do it.  If the filter program gets a copy of the message
to analyze - it can write it somewhere.

Sorry, I haven't written an opensmtpd filter yet.
