Tuta, the world's only quantum-resistant encrypted email provider supports Sender Policy Framework (SPF), Domain-based Message Authentication, Reporting, and Conformance (DMARC),
and Domain Keys Identified Mail (DKIM). While we have supported DKIM for Tuta domains from the start, the demand from our growing
number of users using their own domain required that we also introduce SPF, DKIM and DMARC support for custom domains on our secure email platform.
