Is Exim4 the right software for this?
I have just bought a mobile broadband dongle for my laptop. As the service does not come with an email account, I would like to use my home broadband ISP's SMTP server to send emails. My linux box at home (running debian) has a fixed IP address, and so I just need to configure an MTA (I think?) to accept emails coming via the internet from my laptop and forward to my ISP's SMTP email server for delivery. I am used to command-line linux, but I know very little about the email side of things. Obviously I have a lot of reading to do, but I just wanted to ask which software would be able to do the above? There's not much point in me spending hours RingTFM of the wrong software! Is exim4 the answer?
