LinuxQuestions.org - Nagios not sending email notifications

Greetings,

I'm using Nagios to monitor a localhost running CentOS. I have enabled the following features in my config files in an attempt to allow email notifications:

1. Notifications enabled in main nagios.cfg file, as evidenced:

# NOTIFICATIONS OPTION
# This determines whether or not Nagios will sent out any host or
# service notifications when it is initially (re)started.
# Values: 1 = enable notifications, 0 = disable notifications

enable_notifications=1

2. flap-detection-enabled set to 0 in generic_host template and generic_service template (no further overrides of this setting in objects inheriting from these templates)

3. Notification_period on template 'linux_server' (default template for localhost object) set to 24x7

4. notifications_enabled set to 1 in all previously mentioned templates and within the specific service "MyDocs Age Check 7", as evidenced:

define service{
use local-service
host_name localhost
service_description MyDocs Age Check7
check_command check_file_ages_in_directory!"/home/nagios/Documents /home/nagios/Downloads"
notifications_enabled 1
contacts dburt
}

5. Further, I have received confirmation from the Nagios CGI that notifications were triggered for my alert:

as well as in the nagios.log file:

so my question....

Is this a problem with Nagios?? (which appears to believe it sent an email)

or can I safely assume Nagios has done its job, and this is a problem somewhere else? (firewalls, mail servers, etc.)

btw - it's not a spam filter on my email account, I'm using Gmail's "All Mail" folder.

Thanks!
