I am now trying to set up my new server. Today, after testing the email, something is not right. Yahoo, Gmail and other mails worked fine except that I cannot send email from xxx@myjaring.net or yyy@myjaring.net to admin@mydomain.com (mydomain.com is my main account on this new server). Below is the error I got. Outlook 2007 generated this error message INSTANTLY after attempting to send the email. I searched Google for an hour but could not find any direct answer.
