How to check where an email will be sent to

Hi

We have been trying to send an email to a private individual in the USA and everytime the message bounces back with an undeliverable error- "The e-mail address you entered couldn't be found. Check the address and try resending the message. If the problem continues, please contact your helpdesk."

The person we try to send the email to stated he has had a lot of people comment they have had emails bounced. He stated they moved servers to a different ISP six months ago and that there MX records changed.
Whilst I appreciate DNS records take 24 to 48hours to update 6 months is way to long!!!!

We use Symantec Messagelabs to forward our emails to external receipients...so my question is does our Exchange 2010 server decide where to route the email to or does Symnatec Messagelabs and further more how can I check if our DNS server has got the correct info as far as MX records are concerned.

Thanks for your help!

use mxtoolbox.com to verify your MX/external dns entires

also you can setup smart host address in exchange SEND connector to forward mails on symantec messagelab

Hi

Our smart host is already setup correctly to forward to messagelabs - I was hoping someone could tell me to run a command or something on the exchange server which would tell me if our dns is wrong or indeed if we need to be worried as our emails would arrive at messagelabs and then they will route it correctly to the external receipient....

thanks

open up cmd:

nslookup -t=mx recipientdomain.com

That will tell you which server the email will be going to.
