Now, lets think about the most common mail that will likely end up in that situation: yes, I am talking about spam and viruses. (^-^) They always falsify the sender address. So if you send back a copy of the mail, you will turn into an excellent backscatter source.
Which reminds me that amavis-new and/or fetchmail sometimes can bounce messages in full or partially. And reminds me that I have to check and verify this.
However... bounce messages with full headers are sometimes very useful, for instance, to learn which is the subscribed address to this list that is bouncing. There are some bouncers I have seen that do not copy even the subject line, nor the sended-to address.
Unfortunately there are a lot of broken bouncers out there. As a general rule I don't mind if messages from my internal users bounce. They are authenticated, exist and want to receive bounces. But I do my very best to only accept mails that I can also deliver. -- Sandy List replies only please!
