Setting up a 2nd NetManager (e.g. proxy or backup) to send system mail onwards
If you have other NetManagers, e.g. backup servers or proxy servers, you will want them to send their system reports onwards to your main server rather than delivering to root on the machine itself. To do this, determine your email domain (e.g. mydomain.com) and the IP address of your main NetManager (e.g. 10.0.0.1). Add the following to the netman.conf file:
domain_external="YOUR_EXTERNAL_EMAIL_DOMAIN" mail_relay="10.0.0.1" mail_forward="10.0.0.1"
While you are there, you might want to some/all of the following lines too:
proxy_external="10.0.0.1:3128"- set proxy to enable it to update itself
services_stop="mysqld squid apache imap homed pop3"- disable unused services (don't put
squidin there if it's a proxy server!)
