Hi Grant,
Your contact has the commands "notify-service-by-email" and
"notify-host-by-email" set for the notifications. These should be
present in your commands.cfg file, so we need to see the command_line
definitions for each of these commands - this is the server command-line
that is executed to send you the notifications.
Regards,
Andy
