We are using Office365 for the mails on more of our websites but on the website the setup is made wrong and the websites uses the smpt on the server. As there are more websites on the same server the "Received: from" will be wrong and we risk being catogorised as spam.
We need one you can change on one site and make a description of the setup.
Experienced team specializing in CMS open sources like Wordpress, Drupal, Joomla, and more with latest web trends and standards are ready to start. Thank you!
