Nina, I don't see an MX entry for gibbonsmail.com. (ie. doing 'dig mx gibbonsmail.com +short' returns nothing) You will need one in DNS (and register that domain name, it returns 'no match'). If you've entered one, it may not have propagated yet. This would explain why it can't deliver the mail to those addresses. Ron
