Mail Routing Issues

[Jason Burzenski]

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"

(wish I saved an output before it was changed)

So if I were to nslookup, set type=mx, b.com, it would return some soa
record information and then that canonical name statement.

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

As soon as this change was made, the messages started being sent to
user at b.com again instead of user at www.b.com and everyone was happy.

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.

What was the change?

What is the MX information held on the authoritative DNS server for b.com?
