Zeq Mail is a zero-knowledge encrypted email service built on the Zeq identity system. Every message is encrypted with HITE (AES-256-GCM + KO42 entropy) and authenticated with TESC temporal PLATs before storage. The server never sees plaintext.

Messages are delivered internally between Zeq identities or externally via SMTP with full DKIM, SPF, and DMARC authentication. Inbound mail from Gmail and other providers is received, encrypted, and stored. Outbound mail is sent with cryptographic signing from zeq.dev.

The optional ZSP Shield wraps message bodies through the full Zeq Security Protocol pipeline — adding compression, malware scanning, and temporal authentication on top of HITE encryption.
