After discovering the php mail() function no longer works I have installed a php script that is using the phpmailer system. The problem is it only sends emails to addresses on the same domain, if we try to send to external emails like yahoo.com or other email addresses on different domains they never arrive. We are using the correct SMTP "mail3.mydomain.com" which is an alias of "mail3.m****here.biz" and authentication with the correct unsername and password. With codes and warnings on we can see it correctly autheticating and sending the message. We receive the email copy correctly on the same domain but external domains receive no emails from our script. A support ticket has been lodged (BJU-53702-125), waiting anxiously for a fix or suggestions. Thank you.
