Lady was running exchange. She had the Symantec virus/spam/crap filter for it installed.. All email to her was bouncing with a 550 spam site deny.
We jerked around with it for quite some time before we realized that one of the dnsbl's that the Symantec product was using was returning positive for ALL queries.
This is the risk you run - this product either had it on by default, or it was in a list of options to turn on. End users don't know what it is, and
actually the risk being run is 'not understanding what you are doing' :( mark this admin of mail systems up with the others who blithely use ANY RBL without knowing how/what/where/when it gets made. -Chris
