An employee who uses an @secondarydomain. address sent a message to someone and their mail server did the reverse lookup and bounced the message. The smpt message says, mail.primarydomain.com #5.5.0 smtp;553 sorry, relaying denied from your location and then has to correct IP address listed at the end of that message. Only reason I can see for it to fail to lookup would be the inconsistency between her email address and the mx lookup or whatever resolved to mail.primarydomain.com and not mail.secondarydomain.com?? As you can see, I have only a very basic grasp of what may be going on here.
