Hello Kwame,
Take note that its /var/log/mail.log (there is a dot between mail and
log)
That being said, its still not a reason why your mails should not go out,
do this:
- Edit this line in your /etc/hosts to look like this: 127.0.0.1
localhost.localdomain localhost
- Restart sendmail and restart nagios
It should work if not then
- run nmap -sT -O localhost (if you have nmap installed, install if not)
and post the output.
Regards
