Exchange 5.5 Sp4 immediate NDR for specific domains
Posted on 2003-10-28
When users attempt to send email to anyone at earthlink.net our Exchange server immediately reply’s to the in-house user with a System Administrator report with the following info. It seems to reply so quickly that it doesn’t even have a chance to hit the earthlink mail server.
Could the reply happen this quickly if our company domain is on a black hole list for earthlink? The reason I ask is because a year ago we had an open relay for about a week but like I said that was a year ago.
