Hi,

I am not using SMTP authentication. That is blocked due to Security Defaults.

I am using O365 Connector via the 25 port without authentication. Seems that Vultr blocks the 25 port by default.

Hi @puregraphx,

We are currently looking into your issue, to assist you more effectively, could you please provide us with the diagnostic test reports? You can access the diagnostic test report from?here.

Hi, it seems Vultr closes port 25 by default, so we asked them to open the port on our VPs. After a reboot, we are now able to connect to the Office Connector via port 25.
