Mail Address Semantics is a voluntary convention for naming people, actors and functions, and for addressing resources, facets, and optional interaction preferences through ordinary email addresses while keeping classification, authority, authentication, equivalence, and delivery implementation explicit and external to the address syntax.
Profile in integrations/postfix (install.sh + README), now used by the live deployment. Probe runs every conformance-corpus local-part and the relay negatives against it; tests/test_postfix_profile.py runs it where Docker is available.

mail-address-semantics
Mail Address Semantics is a voluntary convention for naming people, actors and functions, and for addressing resources, facets, and optional interaction preferences through ordinary email addresses while keeping classification, authority, authentication, equivalence, and delivery implementation explicit and external to the address syntax.
This repo holds the normative MAS v0.1 bundle (mas-v0.1-spec/) and a Python
reference experiment (see INTENT.md and workplans/MAS-WP-0002-*).
Parsing is local and deterministic. Discovery is networked. Policy is pure. Delivery remains external.
Layout
| Path | Role |
|---|---|
mas_core/ |
parser, model, generator, statute (schema + semantic lint + inheritance), discovery, policy |
mas_conformance/ |
Shared corpus: spec fixtures (vendored, drift-tested), property cases, statute cases |
mas_cli/ |
mas parse / explain / discover / lint-statute / test |
mas_gateway/ |
Generic inbound mail → MAS event → HTTP (pipe for MTAs, webhook for providers) |
