Hi,

I am sending an email from Microsoft Outlook 2010 (microsoft exchange) to a unix server. I am not receiving the email in server but I am getting the following error in outlook.

Your message:
From: x@y.com
Subject:

Could not be delivered because the domain name was unresolvable:

Unable to resolve route y.com (MX) - *

The following recipients were affected:
x@y.com

Please let me know how to send email from outlook to server.

Thanks
Neethu

Set up a local dns server, and add an entry for the local server.

Would u plz elaborate how to do put the entry of local server in unix ....

That error indicates that the domain in the email address -- y.com in your example -- is not resolvable by the exchange server. The problem is not with the unix server. The exchange server has to be able to "see" y.com.

If this is a test setup, add y.com to the exchange server's hosts file. Check the MS site for the location on your version of Windows, I'm not sure where it's located.

If a "live" situation, then y.com does not have the correct DNS setting to receive mail...no MX record in the zone - if that's the case, no one can send mail to it, not just exchange.

You can add Unix machine name to hosts file in Windows.
File is located at the following location:
C:\Windows\System32\drivers\etc\hosts
