Good idea!  I've only been sending to the perpetrator (which sometimes

I also have a template file which I use to save time.

How do you automate finding the postmaster and ISP?  I cannot seem to
figure it out.

In the case of the "Janet Dove" spam, the two different months included
different headers:

As you can see, in the second they were better at hiding!  But email to
janetdove didn't bounce....  And the Received tells the IP address.

As to authentication, the headers indicate "pm-", probably a PortMaster.
I _know_ PortMasters have both PAP and CHAP authentication.

Yes, email reply is a good start.  But, I would like to add another kind.
And the ISP's had better listen up:

The other kind is a lawsuit.  It costs about $50 for an individual to
file, and $$$ (thousands) for a company to defend.  And for that same
$50, I can sue _both_ the perpetrator, and an uncooperative ISP.

If the ISP fails to authenticate, and/or fails to log and identify the
perpetrator, they are clearly negligent!

We talked about this last year.  If they haven't done it by now, they
have only themselves to blame....
