I have a problem with nagios xi 5.3.0. The notifications are seen in the console but the users are not receiving the email notifications. I have updated to 5.3.0 today

When was your tarball downloaded? Have you seen Notifications Not Sending In XI 5.3.0?

Yes i have seen that and updated to 5.3.0 again. But its not working.
in the phpmailer.log I am getting this error. only one user can receive the emails.But all other users get this error

Code: Select all

method=smtp;host=xxxxxx.xxxx.xxxx;port=25;security=none), Referer: includes/components/xicore/xicore.inc.php > Event Handler Notification Email

SMTP Error: The following recipients failed: [email protected]<p>SMTP server error: 5.1.1 <[email protected]>: Recipient address rejected: User unknown in virtual mailbox table

This message is the response from the destination email server. It doesn't know what to do with the message so it's rejected. Either your sent to: email address is incorrect, or your destination MTA needs some configuration. This problem isn't a Nagios issue per se.

Only one user was able to get email notifications so once i changed the email address of that user to a gmail account. I was able to receive the alerts to the gmail account. But nothing for other users.

Are you sure name resolution is working correctly on the nagios system? No erroneous entries in /etc/hosts or pointed the wrong DNS resolver?

If this is all correct then as stated earlier, it's not a Nagios issue and consequently not in the scope of support. You might try contacting your Email Administrator for assistance.
