Nagios Notifications dont work

[Rook]

The command ->

Code: Select all

which mail

Gave me

Code: Select all

/usr/bin/mail.

I changed the path in the commands.cfg from /bin/mail to /usr/bin/mail.

Nagios log is showing:

[1550781328] EXTERNAL COMMAND: SEND_CUSTOM_SVC_NOTIFICATION;HOST;Free Space VolGroup-lv_root;0;Nagios Admin;q

No more errors, but the mailbox is not receiving any mails.

Is there anything else i can check?.

Make sure postfix is running

Code: Select all

systemctl status postfix

and you can look in the mail log

Code: Select all

tail -f /var/log/mail.log

it seems i also had sendmail running on port 25.

Purged everything from sendmail and now postfix is running smoothly.

I just received mail the mailbox.

I want to thank you for the quick support.

You can close this case.
