+
+#### Maildirfilter file - vfilter
+# ATTENTION: the syntax for maildirfilter values is the following:
+# the # sign, followed by a space, followed by a M (uppercase), then a modification time value
+# (you need to change this when you change the regexps) made of a maximum of 10 digits, then a
+# space again and an arbitrary number of regexps (a regexp always starts with /^ and ends with
