The RFCs cover received headers for SMTP and RFCs strive to be black and white.  Discussing things as gray area is an argument that Bill Clinton was famous for but doesn't really hold a place in discussing technology covered by The point of SA's trusted configuration is that you "trust" the headers.  In this case, he's saying he doesn't trust the headers because they are omitting important information but that they aren't lying, just lying by ommissions.   To me, this says "I can't trust those headers" and you need to pull back your trust circle which in this case will ruin much of the rules SA uses for pathway analysis (RBLs, rDNS, etc.) Fixing those headers outside SA or fixing the ISP creating those headers are the real solutions. regards, KAM -- Kevin A.
