2.8 - Fight spam your way

• CompuAuth added for Microsoft emails as verification
• Spam rules in Advanced settings
  • 57 rule weights configurable — [spamrules] in advanced.conf; applies to newly scored mail only, stored verdicts untouched
  • New spam rules - read more providers' headers: Barracuda (X-Barracuda-Spam-Status), Proofpoint incl. iCloud (X-Proofpoint-Spam-Details), Google Workspace (X-Gm-Spam, X-Gm-Phishy), Yandex and GMX/Web.de (X-UI-Filterresults). More hacked website fingerprints included.
• UI improvements
  • Advanced settings - groups alphabetically sorted - schema, file, and reference all in one order
  • Group headings + explainers — "DKIM / DNS" style titles with one-line docs, in the Settings reference and as comments in the seeded file
  • Avatars fetched at 2× display size - sharp on HiDPI, ~KBs/year cost
  • Unified mail verifications badges (DKIM, SPF, ARC, DMARC, COMPUAUTH) and clear explainers added as tooltips
• Bug fixes
  • Spam threshold floor now 1 - 0 would have marked every message (clean mail scores exactly 0)
  • ARC verification bug fix
