Email Notifications not working

[ceh]

It was intially /bin/mail and it did not work so I changed it to /usr/sbin/sendmail and it also did not work.

Which user does nagios uses to send mail because the nagios user is unable to send mail.

Its the problem with the mail configuration so after configuring postfix with masquerading mails started going with nagios user.

Excellent. Yes, it is the nagios user that sends the mail
