How Do I Enable Inbound Spam Filtering?

To manage your domain's inbound spam filtering settings you will need to navigate to the Domain Settings page for your domain. 

If you're using the classic UI (options across the top, with a silver background), use the following instructions:

  • Click the Domains tab within your Mailgun Control Panel.
  • Click on your specific domain's name
  • Under the Domain Settings section, the Inbound Spam Filter settings will be available. 
  • To change these settings, click on the pencil icon. 
  • Choose your preferred Spam filtering option and click Save Spam Settings.

If you're using the beta UI (options displayed down the left-hand side on a dark column), use the following instructions:

  • Click on Messages on the left-hand side of your Mailgun dashboard.
  • On the following page click on your specific domain and click on Settings on the far right-hand side.
  • Under Domain Settings the option Inbound Spam Filter will be available.
  • To change these settings, click on Edit
  • Choose your preferred Spam filtering option and click Save Spam Settings.

We provide 3 different methods for processing inbound spam:

  1. No filtering (this is the default setting)
  2. Block detected spam (this is recommended)
  3. Deliver spam, but add X-Mailgun-SFlag and X-Mailgun-SScore headers. 

If you are using our Routes feature to handle inbound email requests, it is highly recommended that you select option 2Block detected spam.

Inbound messages that are being routed to an email address or POSTed to a URL will pass through our outbound spam filters, so If you choose not to enable inbound spam filtering, spam messages that are sent to you may get caught in our outbound spam filter, resulting in your domain being disabled. This is why we recommend option 2.

Note: You need to add Mailgun MX records for inbound messages.
