I configured nagios and postfix, but there is something that doesn't work in mail notification.

When i send a test email from the webgui, this email is sent and arrives correctly, but if i try to configure an automatic notification, the mail il sent to a "strange" address...

In maillog I've:

Test email

Code: Select all

Sep  6 09:47:23 nagios postfix/qmgr[15230]: 40871BFCC1: from=<[email protected]>, size=658, nrcpt=1 (queue active)

Are you also able to post your email command definition from commands.cfg? Usually called notify-by-email .

 /usr/bin/printf "%b" "***** Nagios/Socbox *****\n\nNotification Type: $NOTIFICATIONTYPE$\nHost: $HOSTNAME$\nState: $HOSTSTATE$\nAddress: $HOSTADDRESS$\nInfo: $HOSTOUTPUT$\n\nDate/Time: $LONGDATETIME$\n" | /bin/mail -s "** $NOTIFICATIONTYPE$ Host Alert: $HOSTNAME$ is $HOSTSTATE$ **" $CONTACTEMAIL$

Hello, I changed the command, but the maillog remain empty, no notification arrives to postfix

First of all change it back to /bin/mail, you were already using the right mail client for your OS.

The problem is this: When nagios outputs the character "$" from a macro that means one of two things, either a. the macro is empty or b. the macro has been typed wrong. We can see that your $CONTACTEMAIL$ macro has been typed correctly so it's not problem b. The fact you are getting $@domain is really weird because normally you would get only "$" and nothing else, are there any special characters in your admins name?
