Destination server for recepient could not be found in DNS error??

[shakatak]

Hello,

I am receiving the following message when I try to send e-mail to a user in our South Africa office, "The destination server for this recipient could not be found in Domain Name Service (DNS). Please verify the email address and retry. If that fails, contact your administrator."

Other users in that office can receive e-mail from our corporate headquarters; however, only one specific user is unable to receive our e-mail messages. I've confirmed the correct spelling of the e-mail address and the user's e-mail settings are working correctly according to our IT contact in the SA office but the user is still unable to receive e-mail messages.

Is there something I'm missing? I've checked our AV server to see if it's on a blacklist and it's not. As an extra measure, I added the domain to our Whitelist and it is not on a blacklist on the user's end (ISP).

E-mail goes through our Exchange Server and is sent to their ISP account where they retrieve it via Outlook 2002. Any help would be greatly appreciated as this is driving me crazy.

Thank you!!

Seems like there's got to be a typo in the domain portion of the email address. I know you already checked, but that's the most likely reason. Maybe the user just has a bad reply address? Have you made sure that the address that resolves in your local mail client is coming from the right place? Perhaps there is a bad entry in a shared address book? The latter is the most likely cause. Send an email out that gets bounced, then open your Sent items and examine the header and the destination address. See if there's a typo there.

But...I've personally seen this happen a few days ago, and the email address was perfect.
