Chatmail makes e-mail fun, secure and instant

Chatmail aims to comprehensively modernize the e-mail system to become fast, reliable and secure.

It involves two key complementary project areas:

  • chatmail relay is the main template to deploy a minimal and fast e-mail server providing instant onboarding and cryptographically secured interoperability.

  • chatmail core Rust library serves a higher level chat messaging API and automatically manages DNS, TLS, HTTPS, SMTP, IMAP, MIME, OpenPGP and Iroh-based Peer-to-Peer realtime messaging, and includes the SecureJoin protocol for protection against active attacks (MITM attacks).

Both areas have undergone several independent security audits and analysis and are actively developed.
