Hosting your own mailserver?
It easy sometimes sometimes you sitting there trying to figure why the hell will Microsoft only connect and then quit. And not sending without any change to the mail-server. Updating the server looking through the config. Looking at the certificate. And nothing.
And starting to think that Microsoft is a shit mail company. Because google, yahoo and every other service i tried to send to my own server worked.
Everyone else will send to my server. And I have one that send email to me that use Microsoft.
After a few hours troubleshooting. I finely found the problem.
Drum role .....
IT was the DNS!! 😂
