==== 5.4 Adding Mailcow acct to your phone in DAVx⁵ ====

<ol style="list-style-type: decimal;">
<li><p>Open the '''DAVx⁵''' app on your Android phone.</p></li>
<li><p>Tap on '''Add account''' to set up a new connection. ⊕</p></li>
<li><p>Choose “Login with URL and username”.</p></li>
<li><p>In the '''Base URL''' field, enter one of the following:</p>
<ul>
<li>Your server’s local IP address (e.g., <code>https://192.168.5.3</code>) or hostname (<code>https://mailserver.home.arpa</code>)</li></ul>

<blockquote><p>''Note:'' Use <code>https://</code> at the beginning of the URL for a secure connection. If it bitches at you, use <code>http://</code> - we’re connecting to this via OpenVPN which provides incredibly secure encryption anyway.</p></blockquote></li>
<li><p>Enter your login credentials:</p>
<ul>
<li>'''Username:''' Your full email address (e.g., <code>user@yourdomain.com</code>)</li>
<li>'''Password:''' Your mailcow account password</li></ul>
</li>
<li><p>Tap '''Login''' or '''Next''' to proceed.</p></li>
<li><p>If you see a certificate warning (due to a self-signed certificate), hit '''ACCEPT ''', this is your server. If you misfollowed something here so bad that you even have the ability to connect to someone else’s server right now, you amaze me more than the [https://expandingdan.substack.com/p/steely-dan-second-arrangement-erased-interview assistant engineer on the set of Gaucho].</p></li></ol>

<blockquote>'''NOTE:''' Self-signed certificates are common &amp; normal when setting up a home self managed server. They are not normal on the regular internet.

The entire point of a certificate is that a trusted certificate authority has deemed them to be them. When you go to amazon.com, someone authoritative is vouching that they are actually amazon, so some scammer can’t pretend to be amazon.com tomorrow.

For that authority to be able to vouch for amazon, they have to be able to '''ACCESS''' amazon.

We aren’t letting anyone access our server; and that’s the point. It’s only open via VPN - therefore, we can’t get a real certificate. You could open the port temporarily, and then close it right after you get the certificate, but that just feels dirty.

It’s fine to accept this warning for your OWN server; but don’t let this fly when you’re putting your credit card details or bank password into someone else’s website.
