Contest Brief

I am in need of a freelancer who can fix errors that I am experiencing when sending emails to Gmail and Outlook. The errors are occurring specifically with other email providers like Outlook, Gmail, Hotmail.
The project is done when I can send emails from my own server (ubuntu) to these providers succefully without geting an error message.

Example of an error message to gmail-emailadress:
