Hello jsmurphy, yea i did restart nagios after changing email address in contacts.cfg ..... Also in the past i installed the nagios-3.2.3 and plugins-1.4.11 The email notifications were working fine at that time. SO i thought may be email notification works different in nagios-3.4.4 with plugins-1.4...
