Anti-spam approach	Connection-level blocking of known spam-sending infrastructure before a message is accepted, followed by content-based scoring of accepted mail with a threshold that routes high-scoring messages to Spam; the filter adapts per user from Report spam / Not spam / delete / archive actions. Documented on the vendor's own Stop Spam help page as analysing message content server-side, consistent with a provider that holds the encryption keys and makes no zero-access claim.	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.
