I installed postfix server on Ubuntu 16.04 using a youtube video from 'randomthoughts'. All of the testing and everything worked just fine, still does. When I try to use Outlook to connect to my email account on my server, I get nothing. Outlook says it was rejected, the logs on the server do not even reflect that a connection was attempted. I have checked /var/logs/syslog, /var/logs/mail.log, /var/logs/mail.err, /var/logs/auth.log. I have rechecked my setup step by step and still cannot connect. This does not only happen through Outlook, but through Thunderbird which is actually on the server. After several days of this, I am at a total loss, and have no idea where to look next. Any help would be appreciated.
