SMTP-Server, Port, Verschluesselung, Zugang und Absender unter Mehr -> Erinnerungen, gespeichert in der neuen Tabelle app_setting. Das Passwort liegt mit AES-256-GCM verschluesselt (Schluessel aus BETTER_AUTH_SECRET), wird nie angezeigt und nicht exportiert. Die .env hat weiter Vorrang. Der Zeitplan laeuft jetzt immer und prueft je Durchlauf, ob ein Server da ist. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
