<p><font face="Calibri">I am having difficulty configuring reverse
DNS. This has been a problem for over a year between my
server(s) and my ISP, AT&T. Specifically, I cannot eMail
to any recipient that requires rDNS verification, e.g.,
SBCglobal.net, Comcast.net, or AOL. Very frustrating.<br>
<br>
Two examples of dig:<br>
<br>
# dig -t mx alpha.archaxis.net<br>
ANSWER: 0, AUTHORITY: 1, <br>
<br>
Why does this first example, digging the FQDN of
alpha.archaxis.net reports one authority but no answers?<br>
<br>
# dig -t mx archaxis.net<br>
ANSWER: 2, AUTHORITY: 0, <br>
<br>
. . .yet this second example. digging the FQDN of archaxis.net
reports no authority but 2 answers?<br>
<br>
(The) ;; ANSWER SECTION: (of both examples) reports: <br>
archaxis.net. 10800 IN MX 30
bravo.archaxis.net.<br>
archaxis.net. 10800 IN MX 20
alpha.archaxis.net.<br>
<br>
In both cases, the reported server is an AT&T server ;;
SERVER: 68.94.157.9#53<br>
. . .why shouldn’t this “point” to my server, 162.202.233.81 and
not AT&T’s?<br>
<br>
I have coded my BIND 9 in-addr.arpa zone file as follows:<br>
<br>
</font><font face="Calibri">$ORIGIN 233.202.162.in-addr.arpa.</font><br>
<font face="Calibri">$TTL 3h</font><br>
<font face="Calibri">@ IN SOA ns1.archaxis.net.

<br>
<font face="Calibri">What is wrong? Is this my problem, or with
AT&T?<br>
