I got to thinking about Mutt again and what I didn’t like about it. One of my main complaints is that it relies on postfix and relays through your local machine. I would prefer if it were able to send outgoing through one of my many domains, my ISP, etc. Granted I still have a few other complaints with Mutt, but this tutorial will take care of the mail relaying anyway.

In this tutorial I’ll outline installing, configuring and using ESMTP to handle your outgoing mail. This will allow you to send your email, via Mutt, through gmail, your ISP, or some other mail relay that you have access to. I’ll outline using gmail here, but you should easily be able to customize it for your own needs.
