E-mail not reaching one recipient...

Setup:
Dell PowerEdge Server [new], Microsoft Windows Server 2003 Standard, Exchange Server 2003 Enterprise Edition, ADSL from Qwest behind a Actiontech modem/router.

Issue/Question:
We have been sending e-mails to a specific e-mail address for the past year, and the recipient has always received them.  On 02/03/2005, we deployed our own e-mail server so our ISP no longer hosts our mail accounts.  Now, it appears all but one person is receiving the e-mail.  We have sent e-mails from other accounts to the one who is not receiving them form our domain, and she does get them.  Can anyone provide some input on this?

Thanks!

Can you make sure you are logging SMTP?  Open System Manager, find your server and look through protocaols.  Right-click SMTP and choose properties.  Enable logging on the SMTP Virtual Server.  It will dump it to C:\WINDOWS\System32\LogFiles by default, in a folder like \smtpsv1.  Search on the IP address of the target mail server and look for more info.

Could be they have a SPAM filter that drops your connection (I had a run in with one of these)?  Could alo be they do some sort of Reverse DNS check and you don't have it set up?  Hopefully, log information can help you determine what your Exchange Server thinks is the problem.

Steve,

Your comments above got me to checking various areas of my SMTP setup and I noted in error in the "fully qualified domain name".  I corrected it, stopped and restarted the SMTP service...and the problem was fixed.  I sent an e-mail and received a verificcation.


THANK YOU!!!!!!!!!!!!!!!!!!!
