HELP : Mail Delivery Failure!

[Mahmoud]

Dear,
I have setup my Outlook 2003 with 3 Accounts: My ISP Mail, My Hotmail and my
Internal Exchange Server 2003 E-Mail.

I Added the MX record of the Exchange Server in the DNS of Exchange Server
and the A record is xist for that Server
I Added the DNS IP to my Preferred DNS settings on my computer (That I Have
the Outlook 2003 installed). and made my ISP Mail Account the default mail
account.
Every time i send e-mail to any of the Exchange server e-mail, it gives me a
Mail Delivery Failed message tell :

This message was created automatically by mail delivery software.

A message that you sent could not be delivered to one or more of its
recipients. This is a permanent error. The following address(es) failed:

***@LocalNet

unrouteable mail domain "localnet"

------ This is a copy of the message, including all the headers. ------

Return-path: <***@iqaratmisr.com>

Received: from [62.241.135.163] (helo=mahmoud)

by premiere.use-trade.com with esmtp (Exim 4.52)

NOTE: ***@iqaratmisr.com is my ISP Account which is the default
E-Mail I Send using it
LocalNet : is the Internal domain with my Exchange Server manage
***@LocalNet: is an Internal e-mail I sent to it

Why would you expect your ISP to be able to resolve your internal domain
name? When you set your ISP account as the *default* account, that means
all messages by default will be sent via that account. Is there a reason
that your ISP account has to be your default account?

Confused by some of your statements....

"Added the MX record of the Exchange Server in the DNS of Exchange
Server" - why? Only needed in your public dns server so that external email
servers can send mail to you.

"Added the DNS IP to my Preferred DNS settings on my computer " - whose dns
server ip? This should be your internal dns server. Your internal dns
infrastructure should handle your internal/external host name resolution.

Within your mail accounts setup you would specify the smtp server to use.
