Getting returned E-Mails from .KR domains

Hello, I am a new IT at a small company, We are running exchange 2003 on a windows 2003 small business server. I am very un-familiar with Exchange.

The problem we are having is we keep getting returned emails when trying to send to .kr (korea) domains and it's very important we get this working. Here are the two error messages we keep getting.


1.

            The e-mail account does not exist at the organization this message was sent to.  Check the e-mail address, or contact the recipient directly to find out the correct address.

1. Could be that the recipient is blocking traffic that does not have a valid Reverse DNS record.
See these links:
http://www.amset.info/exchange/dnsconfig.asp
http://www.amset.info/exchange/dynamicip.asp
http://www.amset.info/exchange/smtp-connector.asp

You may need to create a connector to handle messages to this particular domain. See the 3rd link above.

2. The NDR says it all, there are no DNS records for this domain.

i just called my service provider and they looked up my ip, they said they need to create a PTR. does this make sense?

"create a PTR. does this make sense?"
Yes it does. They will be creating a Reverse DNS record.

If the reverse DNS record does not solve your problem, then you will need to create the connector.

"will i be connecting with the KR ?"
You will need to use the SMTP server of your ISP. Check with the ISP to see if they require authentication. From the link above see the Questions section.
