Anti-spam approach	Multi-stage malware and spam scanning at mail transport time, before any optional PGP encryption is applied, combined with SPF, DKIM, DMARC, DNSSEC, DANE and MTA-STS at the protocol level; no content-scanning of already-encrypted mailbox data is described.	SPF, DKIM, DMARC and MTA-STS harden the infrastructure against phishing and spam at the protocol level; Tuta blocks external content (images, videos) in emails by default and warns when the technical sender differs from the visible From address, without scanning encrypted message content.
