<h1>
Matrix To MMS-Over-Email Bridge
</h1>
<p>
I made a friend online while locked-down during COVID who I want to continue communicating with. The problem, though, is that I do not use social media, and chat apps do not work for me no matter how hard I try. So after about a month of back-and-forth discussing possible solutions, we’ve thought of something that we think will work well for both of us: I’m going to run a <a href="https://matrix.org/">Matrix</a> to <abbr title="Multimedia Messaging Service (text message)">MMS</abbr>-over-email bridge on my server.
</p>
<p>
This series will document the process of getting this to work, both because that’s interesting and because it will help me stay on schedule. What follows is a description of how it’s going to work and more detailed posts about it as I go along.
</p>
<h2>
Overview
</h2>
<h3>
Sending
</h3>
<ol>
<li>I send a text to the correct contact.
</li>
<li>My phone provider’s email gateway converts that to an email.
</li>
<li>I receive the message on a different server (~team) because my server (smirkingface) cannot receive mail.
</li>
<li>~team checks the sender address to make sure it’s me, then converts it to a Matrix message.
</li>
<li>Then, acting as a Matrix client, ~team sends the message to my friend (<a href="https://theevilskeleton.gitlab.io/">Tesk</a>).
</li>
</ol>
<h3>
Receiving
</h3>
<ol>
<li>Tesk sends a message to me on Matix.
</li>
<li>smirkingface, acting as a second Matrix client, reads the message and converts it to a multipart/MIME email message.
</li>
<li>smirkingface sends the message via Postfix to my phone provider’s email gateway.
</li>
<li>The Matrix message appears as a text on my flip phone a few minutes later.
</li>
</ol>
<h2>
Details
</h2>
<p>
That whole thing really breaks down to two parts: getting MMS working over email, and getting Matrix working over email. Here are those parts in more detail:
</p>
<ol>
<li>
<a href="1_mms-over-email.gmi">MMS over email</a>
</li>
<li>Matrix over email (coming soon)
</li>
