Modern email delivery,
encrypted by default
EncryptedSMTP is a security-first SMTP relay built for modern infrastructure: strong transport security, operational clarity, and sane defaults.
Encryption-first transport
TLS is treated as the baseline, not an optional extra. We prefer encrypted routes, track encryption outcomes per hop, and highlight weak-TLS signals so you can reduce risk and improve deliverability.
Audit visibility
Understand what happened and why. Delivery results, policy decisions, and security indicators are presented in a clear, searchable trail that supports troubleshooting and compliance workflows.
Secure defaults
Safe-by-default behaviour from day one: abuse resistance, validation hooks, and sensible throttles that help prevent misuse while keeping legitimate sending reliable at scale.
Encrypted content support
Email content is protected in transit with TLS. For true end-to-end privacy, EncryptedSMTP is designed to reliably deliver end-to-end encrypted payloads (PGP/S-MIME or sealed content) without needing access to message bodies or attachments.
