Greetings Everyone,

Due to some super-excessive attacks from Chinese IP addresses, I had to
resort to blocking entire IP ranges from that region.  It has worked out
pretty well, as all our customers are basically US regional businesses.
However, we do have one client that has complained that they are not getting
emails from IBM's Chinese locations.  I have the "from" addresses that are
not making it through; is there any way I can determine a set of IP
addresses from the domain in the FROM addresses, and selectively unblock
those?  We don't have direct access to the mail admins to determine the Ips
from which the messages are being sent, and I'm looking for a quick fix.  I
am very hesitant to unblock the Chinese Ips, because it worked so well in
taking the load off our mail server.

Thanks for any help you can offer!

Marc
