Tunneling SMTP

Good instructions for tunneling Postfix's outgoing mail with OpenSSH.

I don't use my regular SSH id for tunnels like this. If possible, I make a user "tunnel" on the server. To make a passphrase-less id work for tunnel only, put this in the authorized_keys file entry for the key.

command="/bin/false",no-X11-forwarding.no-agent-forwarding,no-pty
