Hello, Team. I'm a new member of this forum.
I am unable to receive any emails from Nagios Core.
I tried sending a test email as well, but I did not receive it; I'm not sure what happened.
I got the error Emails not receiving

Re: I got the error Emails not receiving
Hello @strippedbane,
Since you are using Nagios Core, you are probably running into the issue of modern mail providers not allowing basic authentication anymore. Nagios XI has an OAuth 2 integration which resolves this issue, but Nagios Core does not. For Nagios Core, you will need to use an SMTP server or mail service that permits basic auth.
You can verify that this is your problem by taking a look in /var/log/mail* to see the result of the attempted mail sending. If there is nothing there, you may have misconfigured your mail sending. Here are some resources for setting up email with Nagios Core:
