# ToDo #
########
# - printvariablen bei "grep X-Spam-Status:" korrigieren
# - Mail an antispam@uk-bw.de zusammenfassen: 1 Mail die alle Spammails inkl. Empfaenger beinhaltet
# - Variablen fuer FROM: und RETURN-PATH einrichten
# - evtl. SpamAssassin Spam-Tags (Grund fuer Spam-Klassifizierung) mit in Reports einbauen
# - Mail-Adressen evtl. per LDAP-Abfrage herausfinden
# - in Spamreport XX durch Datum des letzten Spamreports ersetzen
