RE: BIND v9.10.2I have recently converted from a "legacy" DSL service to AT&T's U-verse . . .has been a painful experience. Heretofore, the following from /var/named/named.conf zone "233.202.162.in-addr.arpa" { type master; file "./zonefiles/db.233.202.162.rev"; }; . . .and the contents of the zone configuration file as follows: $TTL 3h @ IN SOA archaxis.net. root.archaxis.net.

AT&T (in all of their surliness) is rejecting email from my SMTP (SendMail) server and issuing the following typical complaint: ----- The following addresses had permanent fatal errors ----- </addressee-changed/@sbcglobal.net> (reason: 550 5.7.1 Connections not accepted from servers without a valid sender domain.alph161 Fix reverse DNS for 162.202.233.81) ----- Transcript of session follows ----- ... while talking to al-ip4-mx-vip1.prodigy.net.:MAIL From:<ron.wingfi...@archaxis.net><<< 550 5.7.1 Connections not accepted from servers without a valid sender domain.alph161 Fix reverse DNS for 162.202.233.81 554 5.0.0 Service unavailable I am at a loss for resolution of this problem. How am I supposed to "Fix reverse DNS"? The configuration scenario previously worked since 2002. Can someone suggest a fix?
