Manage Domains and IPs with Disabled SPF, DKIM and DMARC Checks

In the Domain Level Control Panel, select Incoming - Protection Settings > Filter settings and click on the Manage list of domains and IP addresses with disabled SPF, DKIM, and DMARC checks link at the top of the page.

Domains may be automatically added to the Disabled SPF Domains list if a high number of messages that were quarantined due to failing the SPF check have been released and trained as not spam by the user.
