Hi nickyls,

There is a mailx option which lets you do this which is "-r".

Below is an example:

Code: Select all

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" | /usr/bin/mailx -r [email protected] -s "** $NOTIFICATIONTYPE$ Service Alert: $HOSTALIAS$/$SERVICEDESC$ is $SERVICESTATE$ **" $CONTACTEMAIL$
        }
Kind Regards,

Gary Shergill

Again, Gary is correct, if you leave the -r off it is going to mail from nagios@machine_name

Thank you for quick reply.
But in our instance if i add -r [email protected] the nagios didnt send any notification. The email id [email protected] is provided while configuring Postfix.

Hi nickyls,

If it's no longer sending the notification after adding the "-r", there may be a mistake in your command definition.

Could you please paste the command definition you are using?

Also, just to confirm, are you using mailx?

Thank you.

Kind Regards,
