<P><FONT SIZE=2>I don't know what the actual records look like but I can tell you what the MX query returned. "Canonical name = www.b.com"</FONT></P>
<P><FONT SIZE=2>(wish I saved an output before it was changed)</FONT>
</P>
<P><FONT SIZE=2>So if I were to nslookup, set type=mx, b.com, it would return some soa record information and then that canonical name statement. </FONT></P>
<P><FONT SIZE=2>I asked the admin of the DNS server to change the record to respond with what I was getting from a.com and c.com which looks like: *** Can't find b.com: No answer</FONT></P>
<P><FONT SIZE=2>As soon as this change was made, the messages started being sent to user@b.com again instead of user@www.b.com and everyone was happy. </FONT></P>
<P><FONT SIZE=2>Now b.com is responding with Can't find b.com: No answer from an MX record query and everything is working well but I cant seem to figure out why that happened. </FONT></P>
