Harden ciphermail (listen to only one single interface)

Hi again,

I am very much satisfied with the software - first things first.
Now I wonder, I set up ciphermail as a virtual appliance. Base postfix and ciphermail postfix communicate via VPN GitHub - ntop/n2n: Peer-to-peer VPN.

By default the ciphermail postfix listens to ALL interfaces, which is not needed in my case, since listening to the VPN interface is perfect.
There is a config parameter “inet_interfaces” which can be used for that, but I wonder, should I put it by hand into the ciphermail postfix config file, or is there another predefined solution for that?

Thank you again, Martin.

You should manually configure this in the Postfix config file.
