Nagios Support Forum

Hi Community Members,
I Deploy/Install a Nagios Core in my virtual machine and configure the nagios with Host, Services and for contact. In Nagios console, in notification part i see lots of notifications with my mailing address but notification/alert are not coming on my mailing address that i mention in contact.cfg.

There is something additional part to configure notification for receiving notification on mailing address or it should word after configuration mailing address in contact.cfg ?

Please help on this to understand default scenario for notification.

Thanks in advance...

I read that postfix is required to send out the notification from server to mailing address. So for that i installed and configure the postfix but still issue is same. My mail notification are not going to my mailing address that i mention in contact.cfg file.

i check maillog file using command - # tail -f /var/log/maillog and got output like below -

Please help on this.
What's the issue exactly ?

This isn't a problem with Nagios, but a problem with your server configuration and/or postfix configuration

It appears that smtp.gmail.com is blocking/refusing the connection from your server or doesn't have proper routing and is timing out..

In one of the line I see this Beside other possible issues, you should really have a valid FROM address setup or it could cause rejections as well.
