Auto-notify when postfix requires TLS?

I've set up postfix on CentOS 7, and configured it to require STARTTLS to accept incoming mail. I've run into a couple instances where a server doesn't, for whatever reason, support TLS encryption, and so never issues STARTTLS and the email bounces. Like it should. But the sender typically just gets an 'undeliverable' message from their mail server, and often is not in a position to know what happened, much less do anything about it.
Since the sending server typically issues FROM
before being sent the Must issue a STARTTLS command first
response, the sender's address is potentially available somewhere. Is there any utility to scrape that information and send an auto reply with an explanation and an alternate address or link to a contact form? Any suggestions are appreciated.
