This might be messing things up:

Code: Select all

127.0.0.1       localhost
127.0.0.1       backups
Try changing it to:

Code: Select all

127.0.0.1       localhost backups

I agree, having the same definition on separate lines may cause a problem with resolving hosts. Let us know if you continue to see the issue after making the change.

Hi aleks1,

Just modify the following line in your 'notify-host-email' command definition

/usr/bin/mail instead of this replace with /usr/bin/mailx


pls reply me your status

What does /var/log/maillog show when:
1) you send a manual mail (su to nagios, run "echo "test" | mail -s "test mail" [email protected]")
2) when Nagios attempts to send you a mail

Also, double check the command the service is configured to use, just in case! Nagios can still report a notification event, but if the command it's running fails (bad command name in service config, or bad commandline in the command), it won't log it.

In that case it is a Nagios configuration problem (I thought Nagios had tried to send you mail - my bad!).

Can you show us the service and contact configurations?

It seems that nagios and or the system mailer is unable to resolve the domain deaconsulenze.eu. Can you run the following command and send back the output:

Code: Select all

nslookup -querytype=any deaconsulenze.eu
It may also be due to nagios being unable to read /root/.mail and /root/.mailrc which likely contain the mailers settings on your system and are causing the mail binary to fail any sort of sending
