Mail server with 365

My Passbolt server is not accessible from internet, and SMTP AUTH is enable .
This same count is used with GLPI server, and Zabbix server, and all works.

Hi All,

The probleem looks to be somewhere in Microsoft 365, i tried 2 difrent tenants. And than i make a random adres en tried to use that and that worked directly whit the first test i did. Don’t no excaly what the problem is. It is probably somthing with 2FA and AppPasswords in SMTP auth.

For now i will use the random mailadres and whitelist it in EAC.
