Push comes to shove, this is mail tampering and its against the law. When
harm occurs, the user has the right. The exception is when harm is
considered done at the system. Nonetheless, it does not take away the
problem of litigation potential and it has already started to occur with
moronic systems such as GMAIL.COM getting sued left and right world wide..
SPAMASSASIN was playing with fire and it got bit with spammers suing for
tortious interference. It will be interesting to see the end result of this
case.
My point is simple. Don't screw around with user mail. Please consider
the fact I am not admin. We supply admins with the mail transport and
hosting software. Admins may have a different view on all this and in many
respects, I don't mind saying, it has caused a bigger mess over the years,
especially in the name of spam. Just to ask mail software developers to
begin "modifying" the payload. The day that happens (and the law allows it,
which I doubt), well, you know, shit+fan. Finally, just consider the fact
that to modify the payload, you have to accept the mail and that right there
is where you can get in trouble for being too loose with the delivery of the
mail.

Second, SMTP systems is forbidden from modifying the
payload. Screwing around with the headers is borderline
unethical and runs the risk of >violating some US ECPA
provisions. You got product liability issue to deal
with and I would not promote such concepts. Today
2822.From. Tomorrow, what else? The Subject Line?
The Body? I would not promote such ideas. It is
very dangerous.
There are thousands of deployed spam filters that already do what you
say is so "forbidden", modifying the subject with a [spam] label, unique
ID, or the like. And a great many content and antivirus filters that
modify the message body to eliminate "offensive" content.
Your sacred horse has already left the barn. Most major ISPs and
corporations probably modify 2822 message content for their recipients
in some way.
ISPs may indeed have some common-carrier worries about modifying the
2822 paylod, but they already change the content of messages with
antivirus filters and spam filters. Their customers agree to it in the
terms of service.
