They don't care, Tom. If they did care, I wouldn't be
getting a bunch of nondeliverable email addressed to fake
names.

Example: I'm seeing a bunch of user unknown bounces from my
system for spam email addressed to VzWcwKrdl@ and .Ux.A.jV@

Does any spammer really believe that there really is a user
named .Ux.A.jV?  Why are there so many of these bounces? Why
have these persisted over time? Don't the spammers figure
out that when an email addressed to "VzWcwKrdl" comes back
user unknown, it probably is a bad address?

Again, they don't care.  They are more interested in how
much money they can get from selling X number of names than
in whether those names are active or whether anyone is
actually reading them.

Tom, you don't have to apologize, but it does illustrate my
point. Obviously, your incorrectly configured Mailwasher
message didn't look like a real bounce to a spammer -- so at
the very least, the Mailwasher bounce needs some tweaking.

Where I found that Mailwasher (the beta) was deficient was
that I get email from many addresses that are aliased back
to me.  For example [EMAIL PROTECTED], [EMAIL PROTECTED] -
etc. What I would see is that Mailwasher would bounce back a
message associated with the POP box that I retrieved email
from, which was not what the spammer had.

So for example, spammer has picked up an alias that I used
on posting to usenet - for example, cutename@
mydomain.com.  That address has been configured to forward
to my real address at sbcglobal.net, where I pick it up.
Bounce message goes back NOT with the "cutename"
configuration, but GIVING the spammer the REAL sbcglobal.net
address that they never had in the first place.  An honest
spammer can do nothing at all with that info - they run the
name against their list and find out that they don't have
the name, so the "cutename" stays on.  A devious, dishonest
spammer has now picked up a NEW name, much WORSE for them to
have. (Under the above scheme, I've used "cutename" only in
conjuction with my posts to the one usenet group, and I can
easily disable the name; but getting rid of my primary
sbcglobal.net log in is much more inconvenient).

Maybe the PRO version has solved this issue, but at least
with the beta, the bounce configuration was obviously
counter productive.
