<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 <a moz-do-not-send="true"
href="http://alpha.archaxis.net" target="_blank">alpha.archaxis.net</a><br>
ANSWER: 0, AUTHORITY: 1, <br>
<br>
Why does this first example, digging the FQDN of <a
moz-do-not-send="true"
href="http://alpha.archaxis.net" target="_blank">alpha.archaxis.net</a>
reports one authority but no answers?<br>
<br>
# dig -t mx <a moz-do-not-send="true"
href="http://archaxis.net" target="_blank">archaxis.net</a><br>
ANSWER: 2, AUTHORITY: 0, <br>
<br>
. . .yet this second example. digging the FQDN of <a
moz-do-not-send="true" href="http://archaxis.net"
target="_blank">archaxis.net</a> reports no
authority but 2 answers?<br>
<br>
(The) ;; ANSWER SECTION: (of both examples) reports:
<br>
<a moz-do-not-send="true" href="http://archaxis.net"
target="_blank">archaxis.net</a>.
10800 IN MX 30 <a
moz-do-not-send="true"
href="http://bravo.archaxis.net" target="_blank">bravo.archaxis.net</a>.<br>
<a moz-do-not-send="true" href="http://archaxis.net"
target="_blank">archaxis.net</a>.
10800 IN MX 20 <a
moz-do-not-send="true"
href="http://alpha.archaxis.net" target="_blank">alpha.archaxis.net</a>.<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>

<div>Just to clear up the confusion on this point:</div>
<div>dig is telling you that "<span
style="font-family:calibri">SERVER: 68.94.157.9#53" is
the DNS resolver that your computer used to answer the
DNS question. That server is not part of the answer to
the question. </span></div>
