Auto-Reply Detection

The system automatically filters and marks as read: delivery status notifications, vacation/out-of-office messages, automatic replies. Detection based on subject keywords (multi-language detection: "automatic reply", "out of office", "Abwesenheitsnotiz", "automatická odpoveď", and equivalents in all supported languages), Auto-Submitted header, and Precedence header (bulk/junk).

The system also filters warmup/test emails by detecting subjects containing "delivery test", "speedtest", "[wu-" patterns, and custom headers (X-Warmup-Email, X-Speed-Test).
