Most of our mail from the internet gets through to us.
However, some internet users are unable to send email to us.
As I look at the smtp log the domain name that shows incoming
mail is wrong.
I have tried to clear our DNS cache, purge old entries and refresh the DNS database on on our Windows 2000 server running DNS and Exchange 2000.
For example if I send email to a company called mywidgets.com (not the real name,) it should go to mail.mywidgets.com. The smtp log shows the mail is trying to go to
Incoming email from mywidgets.com should show up in our smtp log at mail.mywidgets.com, it also shows email coming in as tam-exch.mywidgets.com
This is happening to about a dozen companies sending us email from the internet from different domains. This is a small percentage of our business, everything else gets through fine.
I called our internet service provider, they say there is nothing wrong with their DNS entries.
It is unclear if we need to be resolving an Exchange problem or a DNS problem. IF it is a DNS issue we do not see where this is coming from.
I did a trace route for the domain name mail.mywidgets.com and it resolves to the correct ip address.
However, the smtp log for Exchange 2000 is trying to route the mail to a domain called
This is wrong, and this name does not resolve to any ip address.
How do I correct this??
Help! We are loosing business because of this!!!
