E-Mail Delivery Issue

Exchange, Exchange error messages, Non-Delivery Reports

I am new to exchange and
I am having an issue with a mail delivery failure from a recipient on my mail server to a recipient on an external mail account. I notice in the exchng server logs the domain name for the sender-address is showing incorrect on the server only. Has anyone seen this issue before and would you know if it is related to the DNS?

Thanks in advance,

Jamie

I'm not sure what version of Exchange you're using. But there are some tools for Exch2003 that are helpful that I recommend. Also, what is the exact error in the logs and/or bounced emails? What does your internal DNS show for the mail.xxx.com site you're trying to send to? What does an external DNS server show for that same site?

1. SmtpDiag.exe from MS, download and run this at the cli on your Exch server. Very useful.
2. Exchange System Manager > Tools > Message Tracking Center
