# Set Thunderbird to Trust Junk Mail Headers

Spam filtering and other [email authentication](https://www.inmotionhosting.com/support/email/strengthen-overall-email-authentication/) methods help protect you against [phishing scams](https://www.inmotionhosting.com/support/security/identifying-phishing-scams/) such as the [“on this day I hacked your OS” email](https://www.inmotionhosting.com/support/email/scam-email-on-this-day-i-hacked-your-os/). The [Spam Filters cPanel plugin](https://www.inmotionhosting.com/support/email/spamassassin-fighting-spam/) (formerly called: *SpamAssassin*) adds headers to emails marked as spam. This allows email clients like Thunderbird to filter flagged emails that are pulled from the web server based on [meta information](https://www.inmotionhosting.com/support/email/view-full-email-information-thunderbird/).

Below we cover two settings to improve junk filtering in Thunderbird:

- [Trust Junk Mail Headers](#trust)
- [Global Junk Settings](#global)
