Resolved Not everyone is receiving an Email

[JdoubleM]

Server operating system version

I don't know

Plesk version and microupdate number

18.0.?

Hello everyone,
I'm pretty new to Plesk and everything around.
I set up a Forum on my Webspace with Plesk and so far everything was fine.

Now, people of course try to register themselves on my website and people using Gmail receive their confirmation email.
People using Outlook for example are not receiving a mail.

Is it even a problem I could solve in Plesk?
Maybe someone has an idea

Are you subscribed to Microsoft SNDS Sign in to your Microsoft account? Maybe your server is blocked by MS because the IP has a bad reputation? Sometimes they block complete network segments, because some spammers were caught. Your server may be affected. In that case, a delisting request can be sent to Sign in to your account

Ahhh I think somehow its blocked. I'll send them a delisting request if thats the case.
Thank you for the fast help!
