    Hello,

    I have an issue with using Office 365 direct send with a connector in my Exchange portal.

    When setting the SMTP server to my 365 MX record, upon testing the page just spins forever and does not refresh.

    I have checked my web server IP and it is not in any black lists.

    Has anyone got this working before or able to point me in the direction of viewing the logs?

    Thank you

    Hi, the problem could be the List-unsubscribe header which is sometime blocked. We need to ad an exception for that header when using office 365.

    If you can modify the PHP code of the plugin for a test, on line 777 of plugin.php, latest version of newsletter, change List-Unsubscribe to X-List-Unsubscribe

    Let me know, Stefano.
