Users are unable to send email to @tampabay.rr.com email address. All other emails are sending fine. Users recieve this error message:

Your message did not reach some or all of the intended recipients.

      Subject:     RE: test
      Sent:     3/26/2002 10:33 AM

The following recipient(s) could not be reached:

      'usmarcor@tampabay.rr.com' on 3/26/2002 10:33 AM
            Unable to deliver the message due to a communications failure
     The MTS-ID of the original message is: c=US;a= ;p=Mustang;l=XCHGSER1-020326153303Z-977


I have tracked the messages and it appears that they are getting out. I can reach the email address by using one of my online email accounts. I checked Domain blocking and no one has added that Domain.

What should I do? Where does the responsibility lie with? Is it my exchange server that I need to look at or my ISP or tampabay.rr.com?

Please and assitance would be greatly accepted!!!!!

It's possible your ISP is the culprit. If you can email from an outside account to that domain, then that is the best place to start, especially if all other outbound emails are working fine. I've had a couple instances like that before, and it turned out a couple our ISP's DNS servers had taken a nap.

It's possible that you have been listed as an open relay. Check out http://ordb.org/ if the site you are sending emails to subscribes to ORDB and you have an open SMTP relay, they will not be able to recieve the message. Also for troubleshooting, you may want to post the message header.
