Nagios - Change "Sent From" address

Hi there,

We have Nagios configured on a Ubuntu VM.  We recently changed Windows domains and now need to update this Nagios VM with the right information.  We have changed the hostname from "forbes.corporate.local" to "cne-mon01vm.int.cgg.com".  Nagios is still working properly, but whenever we get a notification email, it still says it is from "nagios@forbes.corporate.local".  I'd like to change it to say it is from "nagios@cne-mon01vm.int.cgg.com" instead but I can't figure out where to change that.  

Please help!

Thanks,
- Christian

It is in the script that sends the email. Are you using the default alerts or have you added a plugin to get HTML alerts?
Christian PalaciosSenior IT Systems AdministratorAuthor Commented:
I am using the default alerts that use the default commands.  For example this one:

# '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$SERVICEOUTPUT$" | /usr/bin/mail -s "** $NOTIFICATIONTYPE$ Service Alert: $HOSTALIAS$/$SERVICEDESC$ is $SERVICESTATE$ **" $CONTACTEMAIL$
      }

In that case:
To change  the from address you append " -- -f nagios@domain.com", that is without the quotes of course.  So the new lines look like:

/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 $HOSTSTATE$ **" $CONTACTEMAIL$ -- -f nagios@domain.com

and

/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$SERVICEOUTPUT$" | /bin/mail -s "** $NOTIFICATIONTYPE$ Service Alert: $HOSTALIAS$/$SERVICEDESC$ is $SERVICESTATE$ **" $CONTACTEMAIL$  -- -f nagios@domain.com
