Thanks for sharing this.

I query the wisdom of using "return message".

In the event that a trojan forges the sender address (eg using valid
address book entries), surely you risk sending a live virus 'back' to
an innocent member of the infected sender's address book?

Maybe it would be better to just return the original headers so that
the "sender" can verify if the source was really them. You can then
produce your stored message as evidence on request.
