Ideally, the reflector would enable SMTP+DANE client and server validation 
tests. I could foresee the following functionality:
- Have the several reflector sub-domains configured with various types of TLSA 
records on the domain MX records (PKIX-EE, DANE-TA, and DANE-EE)
- Have an email address that maps to the various test domains to enable inbound 
testing using the various DANE validation types.
- Upon successfully receiving a test message, the reflector MTA would respond 
to the original "From" address on the incoming mail, and provide the SMTP 
client cert data (if provided by the SMTP client).
- When the email response is attempted, a DANE TLSA lookup for the recipient 
domain should be attempted.
        - If the "From" domain TLSA record doesn't exist for the recipient 
domain, or the TLSA validation fails, a message would be sent stating what the 
failure was.
        - If the "From" TLSA record exists and validation succeeds, a success 
message is sent to the client.

Sincerely,

Kevin San Diego
