temojen's Journal: ESMTP Relaying?

I have a residential ISP (the cable company) and fetch my mail via POP3. I can check my email anywhere, but I can only send email from within their network, in the same city. If I take my laptop out of town or to a hotspot that uses the other major ISP in town (the phone company), I cannot send email.

I am currently in the process of frankensteining an ancient laptop to act as a personal webserver. Does anyone know of a very small linux application that can accept SSL'd and Authenticated ESMTP connections and forward mail on to the ISP's outgoing mailhost? I'm looking for something similar to ssmtp, but able to accept SSL ESMTP AUTH connections. There will be no scripting interpreters on the laptop, so PERL, Python, Ruby, etc are out.

why not use ssh?

So you make an ssh connection to your laptop, which forwards the port to your ISP's mail server. Should be a one-liner for a UNIX variant... Easy and secure.

I want to make it usable by a household member who will not be able to figure out how to use SSH, and I don't want to have to set up a tunnel every time I send mail.

Re:

Then you could just use straight port-forwarding [you forward the smtp port on your 'home' computer to the ISP's smtp port, and then you configure the mail client to connect to your home computer instead. This probably won't work if the connection is encrypted, but it should work seamlessly otherwise.

Then it would be an open spam relay and I'd lose my ISP account.
