I'm stumped. Connects from my mail delivery system are being refused by hotmail, oreilly.com, brics.dk, and a number of other sites. I suspect that I've done something stupid in my DNS and am being rejected by sites that set ALL: PARANOID in /etc/hosts.deny . I don't see my system in the RBL, DUL, or RSS lists. Anyone want to help? The problem system is perens.com, IP is 216.15.108.186 . You should be able to see forward and reverse DNS from outside. Thanks Bruce
