that the default Netsaint (BTW, switch to Nagios if you can)
notification configuration uses /usr/bin/mail to deliver mail, so the
SMTP host is whatever your monitoring host is using.

You should be able to see what's happening with either

tethereal | ethereal port 25 on the Netsaint host Or
inspecting /var/log/maillog for mail from netsaint (the default
sender) Or
from the CLI as the Netsaint user (su netsaint perhaps) run the
Notification command like 


1 Work out what Netsaint is actually doing with notifications by

tsitc> grep notify-by-email /usr/local/netsaint/etc/hosts.cfg
command[notify-by-email]=/usr/bin/printf '%s\n%s\n%s\n%s\n%s' '*****
NetSaint 0.0.7 ***** $SERVICESTATE$ alert/notification'
'Date/Time: $DATETIME$', 'Service: $SERVICEDESC$' 'Host: $HOSTNAME$
Address: $HOSTADDRESS$', 'Additional Info: $OUTPUT$' | /usr/bin/mail -s
'** $NOTIFICATIONTYPE$ alert - $HOSTNAME$/$SERVICEDESC$ is
$SERVICESTATE$ **' $CONTACTEMAIL$

contact[anwsmh]=Stanley
Hopcroft;24x7;24x7;1;1;0;1;1;0;notify-by-email;host-notify-by-email;Stanley@xena


2 then

echo|printf "Hello world!\n" | /usr/bin/mail -v email address of one of
the Contacts 

eg 

tsitc> printf "Hello World!\n" | /usr/bin/mail -v Stanley@Xena

So you are in no doubt now, doubtless.
