v0.1.8

What's changed

Added

• mailvalidator/constants.py — new module exposing SMTP_DEFAULT_PORT, DNS_TIMEOUT, SMTP_TIMEOUT, and HTTP_TIMEOUT constants.
• pytest-mock>=3.12 added to dev extras.

Changed

• models: FullReport deprecated alias removed; use MailReport directly.
• assessor: assess() parameters after the first positional are now keyword-only (enforced by *,).
• cli: check command gains a --timeout / -T option (default 5.0 s); exit code 1 is now raised when the calculated grade is D or F.
• reporter: injectable console parameter on all print_* functions; Console created with highlight=False; save_report() raises ValueError for unsupported extensions.
• print_verdict signature changed from (actions, grade) to (report, *, console=None) — verdict actions and grade are now extracted internally.
• verdict: VerdictSeverity gains LOW (1 pt) and INFO (0 pt) members, aligning the enum with headersvalidator.

Impact

Harmonization pass 2. Migration: rename FullReport → MailReport in any code that imported it directly. The --timeout flag is a new addition with no breaking effect.

v0.1.7

What's changed

Changed

• __init__: added NullHandler on the "mailvalidator" logger so library
  users do not see spurious "No handler found" warnings, consistent with all
  other platform modules.
• CLI: internal variable as_json renamed to json_output across all
  sub-commands, aligning with the platform-wide naming convention.

Impact

Maintenance release. Library users consuming mailvalidator as a Python
dependency will no longer see No handler found for logger "mailvalidator"
warnings. No functional changes to checks, scoring, or output formats.

v0.1.6

What's changed

Added

• PQC Key Exchange check — the TLS section now reports post-quantum
  cryptography readiness for each SMTP server. Uses the vendored
  quantumvalidator module (same pattern as chainvalidator) to probe
  whether a PQC hybrid key exchange group (e.g. X25519MLKEM768) was
  negotiated. Result status: GOOD (PQC-ready), WARNING (classical
  key exchange only), or INFO (probe unavailable — requires OpenSSL ≥ 3.0).
  Appears as a MEDIUM verdict action when the server is not PQC-ready.
• quantumvalidator vendored dependency — added as a git submodule
  under vendor/quantumvalidator (CNSA 2.0, BSI TR-02102-2 standards).

Impact

SMTP servers are now probed for post-quantum cryptography readiness
alongside all existing TLS checks. Servers not using ML-KEM hybrid key
exchange (e.g. X25519MLKEM768) receive a new MEDIUM verdict action,
providing early visibility ahead of CNSA 2.0 deadlines. Requires
OpenSSL ≥ 3.0 on the host for the PQC probe to run.
