@Knack, Looks like something happened to your /usr/bin/mail file. Did you delete it by accident?
[1519065324] wproc: stderr line 01: /bin/sh: /usr/bin/mail: No such file or directory

@Knack, In your notification commands above, try changing:

Code: Select all

/usr/bin/mail -s
to

Code: Select all

/bin/mail -s
Then restart nagios with:

Code: Select all

service nagios restart
Try getting a service check in a critical state and see if you can receive a notification. If that still doesn't work try this command:

Code: Select all

which mail
And show us the output.
