It is ironic that you showed me the mail message because even though it wasn't related, the last line I think says the problem
Mitchell wrote:/root/scripts/autopostgresqlbackup: line 491: mail: command not found
The full command that notify-host-by-email and notify-service-by-email run looks like this:
Code: Select all
/usr/bin/printf "%b" "***** Nagios Monitor XI Alert *****\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 $HOSTSTATE$ **" $CONTACTEMAIL$
So, it also pipes the output to /bin/mail
can I have you run the following to see if it can find mail on your system

okay. this solved the email not being sent issue.
however have another issue now... the FROM email address. mailx is taking the FROM email address nagios@###.###.com (user@hostname). I want to change it to our standards.
on a side note: would you be including the mailx package with next version of XI VM appliance?

You may want to check the man page of your mail version, but you may be able to modify the send commands to add a from header like so
Code: Select all
/usr/bin/printf "%b" "***** Nagios Monitor XI Alert *****\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 [email protected]
Adding
to the end of the commands

Thank you. This worked.
Just FYI, I had to use (- r) for it to work.

Glad you got it working. It kind of depends on the mail version...
