i use phpmailer code that sends e-mails through smtp to the "EDGE" before the "Exchange Server".

it only sends to the local e-mails e.g. xyz@mydomain.com from 123@mydomain.com, but when trying to send to external e-mail abc@otherdomain.com, it fails from the php code that succeed to send locally.


i tried to send from the exchange direct from 123@mydomain.com to abc@otherdomain.com, it sends successfully.

what should i do?
