MAY be spoofed?
In this context, I mean the person (robot) that sent the spam may not
actually use the proper From: header, return path:, etc.

You haven't had to deal with this much, have you?


I occasionally receive "undeliverable" messages from places I don't 
think I sent mail to... never bothered me too much. I took it as an 
"advisory" that my address was being abused....

Then, because I use different addresses for different purposes, I am 
able to do a little research as to to who leaked my address despite of 
their "privacy notice"....


So when using EXITCODE=67 this way, *I* may send an "undeliverable"
message to someone who didn't actually send me anything. The up-side is
that will tell them some process is abusing *their* e-mail address.

Ah.
So you SUPPORT Joe-Jobing.
I hope your access is cancelled because of it.


Nice.


In short, your idea is a bad one.
It was a bad one when I first saw someone else do it about 5 years ago.
And it's a worse one now.
My advice is: Don't.

It's one of those "seemed like a good idea at the time" things.... I did 
some googling for Joe-Jobbing, and see the downside... I've turned that 
part of my recipes off.

Cheers.
