Mail filter not working. Tried different mail filters. None of them are working. Debian Stretch + ISPConfig Version: 3.1.6 I did a fresh install following "The Perfect Server - Debian 9 (Stretch) with Apache, BIND, Dovecot, PureFTPD and ISPConfig 3.1" Everything works fine but I cannot get the mail filter working. Is there something I need to do or check? ### BEGIN FILTER_ID:5 if header :regex ["subject"] [".*test"] { fileinto "myfolder"; stop; } ### END FILTER_ID:5 ### BEGIN FILTER_ID:4 if header :regex ["from"] [".*example\.com"] { fileinto "myfolder"; stop; } ### END FILTER_ID:4
