Sorry if this thread is older, but I ran into a PRIME operational example of this last week that cost one of the techs here a few hours headache.
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 only know it'll help eliminate spam, and they turn it on. Then they generate support load when their email breaks.
Average user, or even sysadmin, doesn't know about dnsbl's. To state that you make a concerted effort to use them nowadays may be false. Spamassassin comes out of the box poking SORBS and adding score if it's in there. I turned it off because of questionable listings, but how many users of SA know how to do that?
