I can confirm this is a real problem. A customer of us has been the designated
"blackhole" for quite a few spams now. The spammer put an address from within
their domain into the "Reply-to:" line. The UCE never touches our systems for
relaying or anything.

Every time a spam happens, their mailserver first gets a load of immediate
bounces. Then they get hammered by the lemmings who reply to the spam
directly. Then the complains start and we get a ton of those too.

The problem is we are almost completely helpless here. We forward the
complaints to the ISP from which the spam really originated, but we are
wasting tons of time on this.

And, whats worse, people have threatened to put the customers domains into the
blacklists.

Spamming is a serious DoS attack for everyone but the "clever" spammer.

This "peer pressure" should make sure it is pressing down on the right guys,
thats what I am saying.
