Greetings and a happy new year,
I still am in a situation where I occasionally need to have an SMTP client (preferable Postfix's) talk through an SSH tunnel. I know we have the smtp(8) client, and we have the pipe(8) client for injecting RFC5322 stuff into commands, but what I need is some form of the smtp(8) client talk to the ssh command (with certain arguments) instead of establishing the TCP connection by itself. The current workaround is to establish SSH port forwarding asynchronously, and that is a fragile setup that I would like to replace by something synchronous that doesn't need to set up TCP tunnels when I can instead have "ssh -W host:port" that talks through stdin/stdout. I haven't seen such a feature in the 3.1 release notes - what needs to happen that smtp can - perhaps via special syntax - be made to talk through a command's stdio rather than through BSD sockets? Thanks. Best regards, Matthias
