Re: New Spam Technique

["nate kelly" <nate.kelly.linux () gmail com>]

I have noticed this same thing 9its hard not to when 200 users are
calling to complain). I built a machine for testing and configured it
with an outlook address book that was full of illegitimate mail
addresses on out domain. I setup a catch all on the exchange server
and sure enough the spam started rolling in addressed to the
illegitimate addresses. I have not had time to look into it further
but I hope this helps.
