<p>In case the certificate chain is incorrect, you can tap on the little info button to show the all certificates. After the certificate details the issuer or “selfSign” is shown. A certificate is self signed when the subject and the issuer are the same. Certificates from a certificate authority (CA) are marked with “<a href="https://tools.ietf.org/html/rfc5280#section-4.2.1.3">keyCertSign</a>”.

Certificates from a certificate authority (CA) are marked with “<a href="https://tools.ietf.org/html/rfc5280#section-4.2.1.3">keyCertSign</a>”. You can find the description of other key usage bits, like <em>cRLSign</em>, via this same link. Certificates found in the Android key store are marked with “Android”.</p>
<p>A valid chain looks like this:</p>
<pre><code>Your certificate &gt; zero or more intermediate certificates &gt; CA (root) certificate marked with &quot;Android&quot;</code></pre>
<p>Note that a certificate chain will always be invalid when no anchor certificate can be found in the Android key store, which is fundamental to S/MIME certificate validation.</p>
<p>Please see <a href="https://support.google.com/pixelphone/answer/2844832?hl=en">here</a> how you can import certificates into the Android key store.</p>
<p>The use of expired keys, inline encrypted/signed messages and hardware security tokens is not supported.</p>
<p>If you are looking for a free (test) S/MIME certificate, see <a href="http://kb.mozillazine.org/Getting_an_SMIME_certificate">here</a> for the options. Please be sure to <a href="https://davidroessli.com/logs/2019/09/free-smime-certificates-in-2019/#update20191219">read this first</a> if you want to request an S/MIME Actalis certificate.</p>
<p>S/MIME certificates can for example be purchased via <a href="https://www.xolphin.com/">Xolphin</a>.</p>
<p>How to extract a public key from a S/MIME certificate:</p>
<pre><code>openssl pkcs12 -in filename.pfx/p12 -clcerts -nokeys -out cert.pem</code></pre>

<p>If a message could not be sent to the recipient, you’ll in most cases receive a non-delivery notification message, a special email, indicating the reason, like user (email address) unknown. FairEmail will decode non-delivery notification messages, so you can see all the details.</p>
<p>Basically, an outgoing message is either in the draft messages folder, the outbox, or the sent messages folder.</p>
