Nagios email notification to Office 365 not working

[mcortada]

Hello,

I just installed Nagios Core 4.2.2 in a new Ubuntu server 16.04 with Postfix.
Contact_group is added in each host and service with 24x7 and so on....


Postfix is configure to relay emails to Office 365. I am able to send a test email using below command, but I don't receive any notification email from Nagios.

$ echo "This is a test email from Ubuntu server" | mail -s "Relay Test Email" [email protected] -a "FROM:[email protected]"


Of course I have been reading but end up confused and lost.

Any help is more than Welcome please.

Thanks in advance

Could you post your command definitions? Thanks!

Command definitions are as follow (notify by email):

# 'notify-host-by-email' command definition
define command{
command_name notify-host-by-email
command_line /usr/bin/printf "%b" "***** Nagios *****\n\nNotification Type: $NOTIFICATIONTYPE$\nHost: $HOSTNAME$\nState: $HOSTSTATE$\nAddress: $HOSTADDRESS$\nInfo: $HOSTOUTPUT$\n\nDate/Time: $LONGDATETIME$\n" | /bin/mail -s "** $NOTIFICATIONTYPE$ Host Alert: $HOSTNAME$ is $HOSTSTATE$ **" $CONTACTEMAIL$
}

# 'notify-service-by-email' command definition
define command{
command_name notify-service-by-email
command_line /usr/bin/printf "%b" "***** Nagios *****\n\nNotification Type: $NOTIFICATIONTYPE$\n\nService: $SERVICEDESC$\nHost: $HOSTALIAS$\nAddress: $HOSTADDRESS$\nState: $SERVICESTATE$\n\nDate/Time: $LONGDATETIME$\n\nAdditional Info:\n\n$SERVICEOUTPUT$\n" | /bin/mail -s "** $NOTIFICATIONTYPE$ Service Alert: $HOSTALIAS$/$SERVICEDESC$ is $SERVICESTATE$ **" $CONTACTEMAIL$
}


Thanks

What is the output of which mail? The core commands as you can see are simply passing the printf data to /bin/mail. If which mail reports /bin/mail, then this should work fine.

Next step, is looking at how you specified the from address. Take a look at when your notification fires in Nagios, and look at /var/log/maillog - if you see something indicating it was rejected, or bounced, then the likely cause is it being blocked due to an invalid sender. You may want to append to your notify-host/service-by-email commands the -a parameter you were passing in your testing.

For example -

Code: Select all

# 'notify-host-by-email' command definition
define command{
command_name notify-host-by-email
command_line /usr/bin/printf "%b" "***** Nagios *****\n\nNotification Type: $NOTIFICATIONTYPE$\nHost: $HOSTNAME$\nState: $HOSTSTATE$\nAddress: $HOSTADDRESS$\nInfo: $HOSTOUTPUT$\n\nDate/Time: $LONGDATETIME$\n" | /bin/mail -s "** $NOTIFICATIONTYPE$ Host Alert: $HOSTNAME$ is $HOSTSTATE$ **" $CONTACTEMAIL$ -a "FROM:[email protected]"
}

This should send the same exact way your testing was.
