Anti-spam approach	Incoming and outgoing messages are automatically analysed by anti-spam, anti-virus and anti-abuse checking routines; the provider's own security-analysis documentation states this applies at the transport layer and that OpenPGP-encrypted message bodies are never visible to the server.	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.
