Looks good except you don't really need an mx record for
www.domain.com... no one in the real world ever sends email to
username@xxxxxxxxxxxxxx; only RaQs <wry grin>.

Nope.

All your nameserver is doing is telling the originating email server to
send mail addressed to user@xxxxxxxxxx to send the email to
3rdparty.com.  And it's doing that by sending an IP address back to the
originating email server.  The originating email server sends the email
to 3rdparty.com's IP# without any information at all about your
nameserver.  That ISP has NO clue.

However it may very well be that your secondary nameserver isn't
properly registered.  Since yo're not using your real domain name, no
one here can help you.

What are your real domain name, the real domain names of all the servers
shown in your examples, and the real names of your nameservers.

Without real information, we CANNOT help you.  That's why you haven't
gotten any good answers.  We can't help you if you hide the facts.

Hiding the facts is useless.  All the information you're hiding must be
readily available and world-readable on the Internet.  If it's not, NO
ONE CAN FIND THE SERVERS.

SO PLEASE STOP BEING SO PROTECTIVE IF YOU WANT US TO HELP YOU.  Yes, I'm
shouting <wry grin>.
