Is there any way to use the old network configuration style (ie. without RHEL6's new network manager) as known from previous CentOS versions? We're having the issue that every additional IP stops working, if we nullroute the primary IP address of a cPanel setup on CentOS 6.
And a second question: Is there an option in WHM/cPanel to change the default IP which is being used by SMTP? The problem is, that it's always using the primary IP address if a client uses PHP's mail() functions, while we would prefer it if it would use some other IP which is bound on the server.
