 <p>Spam filtering, verification of the <a href="https://en.wikipedia.org/wiki/DomainKeys_Identified_Mail">DKIM</a> signature and <a href="https://en.wikipedia.org/wiki/Sender_Policy_Framework">SPF</a> authorization is a task of email servers, not of an email client, which is basically a viewer for messages on an email server. Servers generally have more memory and computing power, so they are much better suited to this task than battery-powered devices. Also, you’ll want spam filtered for all your email clients, possibly including web email, not just for one email client on one device. Moreover, email servers have access to information, like the IP address, etc. of the connecting server, which an email client has no access to. Furthermore, an email server can inspect all messages of all email accounts, while an email client can inspect messages in your email account only.</p>

 <p>Spam filtering based on message headers might have been feasible, but unfortunately this technique is <a href="https://patents.google.com/patent/US7543076">patented by Microsoft</a>.</p>
 <p>Recent versions of FairEmail can filter spam to a certain extent using a message classifier. Please see <a href="#faq163">this FAQ</a> for more information about this.</p>
