+# amavis-local-domains-auto.sh
+#
+# Zweck
+# -----
+# Ersetzt in /etc/amavis/conf.d/50-user die lokale Domains-Definition
+#
+#   @local_domains_maps = ( ["."] );
+#
+# durch eine dynamische Definition, die aus der (effektiv aktiven) Postfix-
+# Konfiguration ermittelt wird (pgsql oder mysql). Damit werden Spam-Header
+# nur für Domains geschrieben, die Postfix tatsächlich als "lokal/relay" kennt.
+#
+# WICHTIG:
+# - Das Skript ändert NUR dann etwas, wenn die Zeile exakt ( ["."] ); ist.
+# - Backups werden IMMER nach /etc/amavis/ geschrieben (nicht neben die Datei).
+# - DB-Typ wird automatisch aus "postconf -n" erkannt (robust inkl. includes).
+#
+# Features
+# --------
+# - Auto-Detect Backend: pgsql | mysql (aus Postfix-Maps)
+# - Optionaler Fallback: wenn DB nicht erkennbar, dann auf ( ["."] ); setzen
+#   (standardmäßig AUS, weil produktiver Betrieb)
+# - Dry-run Modus
+# - Optional reload/restart von amavis
+# - Atomare Aktualisierung (schreibt erst tmp, dann mv)
+#
+# Nutzung
+# -------
+#   sudo ./amavis-local-domains-auto.sh --dry-run
+#   sudo ./amavis-local-domains-auto.sh --apply --reload
+#   sudo ./amavis-local-domains-auto.sh --apply --restart
