Using the Mail Troubleshooter in WHM This demo assumes youve already logged in to WebHost Manager. Lets learn how to use the mail troubleshooter feature in WHM. Click the Email link. Then click the mail troubleshooter link. This is where you can test any email address by tracing its route from this server. Lets trace an email aaddress that would be on this server. Enter an email address in the Email to trace box. Then click Submit. The trace didnt go very far because the email address would be located on this same server. Go back to the mail troubleshooter. Lets enter an email address that we know is not on this server. This time the trace went to a server called smtpin.eastlink.ca and there were no errors in this trace. This email address appears to be working fine. Click the mail troubleshooter link again. This time enter a bogus email address that you know will fail. This time we got an error saying it failed. This is the end of the tutorial. You now know how to check an email address by performing a trace using the email troubleshooter tool in WHM.
