<i>Using</i> mutt is pretty easy once you&#x27;ve set it up.<p>Configuring it to use pgp (way before gpg existed) was a bit of a challenge years ago. I certainly wouldn&#x27;t recommend it to most people today. At the time, most email programs required some technical knowledge to setup, so the difficulty is relative.<p>My point is that these solutions have existed for a <i>long</i> time, even in what many would now call the &quot;earlier&quot; years of email. Even decades ago it was common to have the setup <i>within</i> and organization handled by IT.<p>&#x2F;&#x2F; mutt still wins over more &quot;modern&quot; email software in a lot of ways
