Did you change your email settings in XI Home --> Admin --> (Under system config) click Manage email settings --> Change sendmail to SMTP.

Then add your SMTP host, Port --> username and password if necessary and security.

Take a look at the documentation on SMTP from pages (specifically pages 5-7)
https://assets.nagios.com/downloads/nag ... ios-XI.pdf

Does this help?

Are you able to telnet the exchange server over port 25?

Code: Select all

telnet <ipaddress> 25

Or you could run the check_smtp plugin from Nagios

Code: Select all

 cd /usr/local/nagios/libexec
 ./check_smtp -H hostaddress -p 25

Are you authenticating SMTP?

delivery temporarily suspended

Are you still having issues? The temporary nature of this suggests you need to speak with your mail administrator, whether this is someone in your organization or an external provider.

It's possible there was initially a flood of emails. If you have warnings and criticals resolved, that flood would no longer be causing you to get blocked.

It looks like it's the same issue as before?

status=deferred (delivery temporarily suspended: connect to mailserver[IP]:25: Connection refused)

Did you have a chance to speak to your mail administrator?

It goes back to what @dwhitfield said in his previous post.

If you have warnings and criticals resolved, that flood would no longer be causing you to get blocked.

Do you have a lot of issues on Nagios, which are causing a lot of notifications?
