<P><FONT size=2>Good point Trever, that was my original problem. But I
think you hit the nail on the head with your previous post Antony, stating
that the MX record was pointed to a CNAME. That does sound exactly like
what happened but I'll never be sure. </FONT></P>
<P><FONT size=2>An just for completeness, to answer your questions:</FONT>
</P>
<P><FONT size=2>I asked the DNS admin to 'make the record for b.com respond
exactly like a.com and c.com for an MX query.' The problem was, a.com
and c.com would return NO information about MX whereas b.com would return that
canonical name junk. </FONT></P>
<P><FONT size=2>Posting the real domain names wouldn't have helped anyway
because this is an internal DNS server that is causing my routing problems so
you couldn't have done any testing. :) </FONT></P>
<P><FONT size=2>You do bring about an interesting point and maybe I should now
consider deploying a separate dns service for the purpose of maintaining these
records or work towards repairing the existing internal dns server.
Ideally I would like to have my particular mail routes ignore DNS but since Im
already ignoring DNS from the perspective of the configuration, this does not
seem possible. </FONT></P>
<P><FONT size=2>FYI: I tried removing the resolv.conf file last night to
see what effect it would have on my message routes and what happened was
suprising. All mail simply queued up. Nothing was delivered even
though I have my routes specified as IP addresses. Go
figure.</FONT></P></BLOCKQUOTE></BODY></HTML>
