Nagios Support Forum

Can't seem to get my email notifications to work.
I've added all the parameters I understand are necessary to the "Nifi Group Transmisiones demo" service and to my contacts and am still not getting the emails.
NB I need the notififcations for all the services - I'm just focusing on this one for now just to see if I can make it work.
See attached cfg files.

Thanks
Milo

It's been fixed!
After studying the nagios log (/usr/local/nagios/var/nagios.log) and the sendmail log (/var/log/mail.log)...and some googling, it turned out that the problem was the configuration of/etc/hosts

Thanks
