Hello Exchange Experts,

I have installed my Exchange 2003 Server SP2 with 2 NIC cards, Assigned 1 with Static IP and the other with private IP. my Active Directory Domain name is different than Internet domain names; it's .local.

Everything were working very good till yesterday it's stopped from send internet based emails and no NDR reports comes.

My Static IP is not black listed.
I have more than 5 domain names and hosting packages at networksolutions.com.
I bought POP3 Downloader software to download the emails and deliver theme to internal mailboxes. I setup my Recipient Policy with 2 Addresses 1 @abc.local, the second @domainname.com.
The users who have Internet Mailboxes and Changed their email address to be the Internet Email address as default email address to send emails from his internet email address.

Now I cannot send any internet based email. What can I do?

And is there a need to configure PTR record to my Static IP; if yes what is the name will my IP pointing to?

Thank you for your greate efforts.

We need to nip this one in the bud before it gets out of hand.
You do not want to have this configuration.
Have one IP address only (team the NICs if you want) and make it an internal address.
Put the external IP on the external interface (firewall/router) and route TCP 25 and 443 from there to the internal IP address.

You should never expose the box like that, it's bad practice and leads to DNS/WINS/routing issues down the line that are troublesome to solve.

I completely agree with Mark on this. Now looking at the configuration you have it seems you previously used to have your emails hosted on an external server. You said that it used to work till yesterday and then it stopped. Do you recall what changes were made after which it stopped?
 
I assume that you are still using SMARTHOST solution wherein all your external emails will be sent to an external server which would forward the emails to the internet and also from where you would download the emails onto your internal server using the POP3 software. Am I correct on this?
