Hello,

Am trying to make Postfix and OpenVPN client coexist on the same machine but without luck.
When my VPN is up, a virtual tap0 interface is created.
I tried to bind Postfix to localhost only and then to the eth0 IP but it doesn't want to send nor receive when the VPN is up. So binding is not enough or is just useless (inet_interfaces = localhost or inet_interfaces = 192.168.1.100).

It seems, am going in the wrong direction trying to solve my problem.

PS : the machine has only 1 physical interface (eth0).

Thanks for helping me putting Postfix out of the VPN traffic (if it's possible !)
