if you use the PTR hostname interbusiness.it, then that blocks all of that ISP of which there is a huge number of spammers. >And they seem to keep coming. The common >denominator is the fax number at the bottom of the message. I suppose I >could put that in a body check? that would do it, it they fax number has not been obscured by some hidden characters inside the number. The problem with scanning for the fax number is that it is not anchored to the start of line, so you have to scan every byte of every message to catch a few messages. Content-scanning is very inefficient, and mostly a waste of time.
