You don't fix this, AT&T needs to be told to fix it. I assume you have
static IPv4 addresses? You don't seem to have an MX record at all.
The way AT&T will update this is if your MX record(or backup MX record)
points to this ip address and then they should honor a request to set
the reverse lookup for you.

RE: BIND v9.10.2
I 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. (
2015080601 ; Serial
3h ; Refresh
1h ; Retry
1w ; Expire
1h ) ; Negative cashing TTL
IN NS ns1.archaxis.net.
IN NS ns2.archaxis.net.
1 IN PTR archaxis.net.
1 IN PTR ns1.archaxis.net.
1 IN PTR ns2.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)

<<< 550 5.7.1 Connections not accepted from servers without a valid sender

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?
Thanks,
Ron W.
