Salesfusion (Acquired by SugarCRM) recommends their users set up DKIM authentication for their respective sending domains registered on the Salesfusion platform. DKIM keys help encrypt email messages to prevent the tampering of data by cyberattackers. This can help improve deliverability over time.
To enable DKIM for Salesfusion, contact the SugarCRM support team at firstname.lastname@example.org to help you with the onboarding process.
Salesfusion also recommends that you enable SPF for Salesfusion, for your sending domains.
