Spam mail problem

[Todd Reese]

I'm looking for suggestions on this one.

It has come to my attention that some of the spammers are forging  their
mail as being from [EMAIL PROTECTED]
 and relaying wherever they want.  What is the best way to stop this action
from happening?

I'm already using rbl and orbs to block unwanted sites now.


TIA,
