SMTP problem with mail bouncing back

Greetings,

We have decided to host our own mail using our existing exchange server. I made the changes to our domain record at network solutions to point back to our external IP address.

I contacted our hosting company that hosts our domain and made the changes to the A record and MX record. on the MX record It reads:

tdcb.com. MX IN 1800 exchserver.tdcb.com

our exchange server is named "exchserver" but our local domain is tdcb.local so it's exchserver.tdcb.local. do i need to change the MX record to look like:

tdcb.com. MX IN 1800 exchserver.tdcb.local


The problem is when I send mail to a account on our exchange server it gets bounced back with:

========================================================= This is an automatically generated Delivery Status Notification.

Delivery to the following recipients failed.

bnelson@tdcb.com

Reporting-MTA: dns;hotmail.com Received-From-MTA: dns;mail.hotmail.com Arrival-Date: Sun, 7 Jul 2002 09:47:33 -0700

Final-Recipient: rfc822;bnelson@tdcb.com Action: failed Status: 5.0.0 ========================================================

Any ideas what the problem is?

You need to have your ISP add an A record for your email server. I'll assume it's exchserver (I'd prefer the name mail, but it's up to you)

Your MX record should look like:

  MX IN 1800 exchserver.tdcb.com

or just

  MX IN 1800 exchserver

Either way, external mail servers need to be able to resolve the name (exchserver.tdcb.com) into an IP address.  Using the .local address will NOT work.

That was the problem, After looking further into the A and MX records, I noticed one of my A records was some how deleted. I re-added the record and voila all works,

Thanks for the help.
