Response to: How do you know you were not forwarding SPAM?
I believe that the return addresses were all for
the same address, which was invalid. As a result, I received a lot of "double bounces".
Sneaking a tiny blurb in a bounce message is
possible, but most MTA's mangle them so much
that most technical people I know can't interpret them :-)
