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.	Personal, per-user Bayesian spam filter (SpamAssassin) trained by the user marking mail as spam or not; the training data is stored inside that user's own encrypted vault rather than pooled across the service.
