No. The milter makes various callbacks during the SMTP session. It's documented here: https://www.milter.org/developers/overview The final callback after DATA passes the milter the entire message headers and body, but *only* exactly what was received over the wire. It will *not* include any headers added by Sendmail or the milter, or any other changes to the message. If you want to check for TLS verification, you need to do it outside SpamAssassin and pass the Sendmail macro ${verify} down into MIMEDefang. All in all, a bit of a mess. Regards, David.
