You need to set notification_period and notification_options properly in 
the service object definition, as well as service_notification_period 
and service_notification_options in the contact definition. In addition 
to this, you must also be in the contactgroup which receives 
notifications for the service (it's not enough to be a contact for the 
host to receive notifications for its services). If all of that is set 
up properly you should have a look at the service_notification_command 
and the relevant timeperiods.

'r' is for recovery in notification_options for service objects, as well 
as for service_notification_options for contact objects.

Not when properly configured, no. Does the imap server normally respond 
to PING? check-host-alive is (by default) just a check_ping with more 
lenient values, you know.
