Here is my new idea: if no identification is provided via SMTP, then
before entering the DATA phase, send a DSN to the MAIL FROM. The DSN

SNIPPED
The point is, whether it is a forgery, or a misconfigured server, they
need to fix it, and hopefully getting the nagging DSN every time might
help motivate them.
I think you need to make sure you don't create mail-loops or nag too
often. Read http://ietf.org/rfc/rfc3834.txt -- Recommendations for
Automatic Responses to Electronic Mail - Makes recommendations for
software that automatically responds to incoming electronic mail
messages, including "vacation" response generators, mail filtering
software, email-based information services(Mailing lists which accept
subscription requests via email fall into this category), and other
automatic responders.
I'd also think that you should maybe make it probabilistic and set a
maximum daily quota. You don't want to get 500 reply emails.
