OxiMail is built RFC-first: a method or protocol feature is implemented from the specification text, with the RFC’s own examples as tests, before anything else. This page maps the standards each surface implements. It is a directory, not a conformance certificate — the per-page documentation states behaviour precisely, including the few deliberate, documented deviations (each marked where it occurs).

Mail format and transport

Email authentication and transport security

Implemented in the in-house oximail-auth crate, consumed by the SMTP layer; the operator view is the email authentication page.

​
Legacy protocols

All documented on the legacy protocols page.

Security and authentication

Where OxiMail deviates from a specification, it is deliberate, documented at the point of behaviour, and biased the same way every time: strict on what we accept as valid, honest about what we advertise, loud about what we cannot do — never a silent partial implementation.
