Oh wait, I think I'm wrong. The key+cert files (client-side SSL certs) are not the same as the trust files (which verify the server's SSL cert). Let me take a look, this may require another parameter or I'm missing something. >> This is all nasty, nasty for the user.

There's no problem with specifying an unencrypted authinfo file for a specific server+port+user (or any subset) combination, see `auth-sources'. So the authinfo line would look like this: machine mysmtpserver.com login tzz password mypassword keyfile "~/.keyfile" certfile "~/.certfile" LMI> Uhm. How did that discussion about non-secret credentials go? :-) Look! It's Elvis! (runs away) Ted
