I'm trying to allow TLS SMTP traffic through an ASA. I've got basically the same exact thing happening that's described in this blog post:
https://stomp.colorado.edu/blog/blog/2012/12/31/on-smtp-starttls-and-the-cisco-asa/

However, changing the policy-map to include allow-tls isn't fixing it for me. SMTP connections are still displaying the "220 **********************" banner and "250-XXXXXXXA" that are indicative of the ASA modifying the traffic.

Anyone seen this before or have a suggestion?
