SPAM filter improvements

We are all aware, the battle against Spam email is an ongoing problem.

I recently loaded new features onto our Spam email filter. We thought that it may be good time to point out again what we're doing to continue to battle Spam. Here is a list of the new features available to us:
- Invalid Bounce Suppression. The Spam firewall is now configured to reject all Non-Delivery Receipts (NDRs) except those for messages verified to have been sent or relayed out from SELCO's email server.
- Character Set Blocking. Administrators can determine the action to take on a message based on the language and character set detected in the message itself.
- Reverse DNS Blocking. Administrators can determine the action to take on a message based on the originating country, as determined by a Reverse DNS query of the sender's IP address.
