For email:

    command_line    /usr/bin/printf "%b" "***** Nagios *****\n\nNotification Type: $NOTIFICATIONTYPE$\n\nService: $SERVICEDESC$\nHost: $HOSTALIAS$\nAddress: $HOSTADDRESS$\nState: $SERVICESTATE$\n\nDate/Time: $LONGDATETIME$\n\nAdditional Info:\n\n$SERVICEOUTPUT$" | /bin/mail -s "** $NOTIFICATIONTYPE$ Service Alert: $HOSTALIAS$/$SERVICEDESC$ is $SERVICESTATE$ **" $CONTACTEMAIL$

For XMPP:

    command_line    /usr/bin/printf "%b" "***** Nagios *****\n\nNotification Type: $NOTIFICATIONTYPE$\n\nService: $SERVICEDESC$\nHost: $HOSTALIAS$\nAddress: $HOSTADDRESS$\nState: $SERVICESTATE$\n\nDate/Time: $LONGDATETIME$\n\nAdditional Info:\n\n$SERVICEOUTPUT$" | /usr/bin/freetalk -s /var/log/nagios/notify.scm

Doing this showed that you are correct about it being a permissions
issue: nagios is running as user 'nagios' and group 'nagios', but
the /bin/mail and /usr/bin/freetalk commands are being run in an
environment where it seems that HOME=/root/ - the commands attempt to
access /root/.esmtprc and /root/.freetalk/, respectively, rather than
attempting to access /var/log/nagios/.esmtprc and
/var/log/nagios/.freetalk/ (where /var/log/nagios is HOME for user
nagios).

Obvious kludges are:

* copy the respective dot files to /root/ and either chmod them o+r
or chown them root.nagios;

* modify the command_line to use sudo to ensure /bin/mail and
/usr/bin/freetalk are run as user 'nagios'.

But surely there's a better alternative? What am i missing?
