notifications not being sent

The email notifications stopped working.
How do we trouble shoot the email notification system in Nagiosxi?
This appears to have been working in the recent past via send mail.
Now the only way I can get a test email completed is with smtp / TLS with no user ID and password.
This system has been and is allowed to relay to our exchange server.

This system has been and is allowed to relay to our exchange server.

Exchange/Office365 is a bit picky when it comes to who it allows to connect. If you set up the XI server as an allowed relay, you should configure the postfix on that XI server to relay through the exchange server and, similarly, have Nagios XI connect to the local postfix (which again, is relaying traffic to the exchange server).

Or, if your org uses an internal relay to send/receive email, have Nagios XI talk to that. Point being, having Nagios XI talk directly to the exchange server often results in the issues you're seeing.
