Unable to send email
First let me tell ya my setup:1) Dedicated Windows 2003 server hosting my site.
2) Hosting my email on another server (directadmin).
On my site I have a form for customers to fill out, for some reason I can set any email on the script BUT my domain email address and it will work fine. If I set it to my own I get the message below:
This is an automatically generated Delivery Status Notification.
Delivery to the following recipients failed.
myemail@mydomainname.com
-------------------
Final-Recipient: rfc822;myemail@mydomainname.com
Action: failed
Status: 5.5.0
Diagnostic-Code: smtp;550 authentication required
It looks like it's trying to authenticate on my windows server
