when DKIM, SPF or [DMARC](https://en.wikipedia.org/wiki/DMARC) authentication failed on the receiving server.
You can enable/disable [authentication verification](https://en.wikipedia.org/wiki/Email_authentication) in the display settings.
The feature depends on the header [Authentication-Results](https://datatracker.ietf.org/doc/html/rfc7601), which the receiving email server should add.
If the email server doesn't add an *Authentication-Results*, which is optional,
you can enable native DKIM in the debug panel, which appears when you enable debug mode in the miscellaneous settings tab page (last option).
Please be aware that this option will increase both data and battery usage.
FairEmail can show a warning flag too if the domain name of the (reply) email address of the sender does not define an MX record pointing to an email server.
This can be enabled in the receive settings. Be aware that this will slow down synchronization of messages significantly.

<p>If the domain name of the sender and the domain name of the reply address differ, the warning flag will be shown too because this is most often the case with phishing messages. If desired, this can be disabled in the receive settings (since version 1.1506).</p>
<p>If legitimate messages are failing authentication, you should notify the sender because this will result in a high risk of messages ending up in the spam folder. Moreover, without proper authentication there is a risk the sender will be impersonated.
