+#   AERC_MIME_TYPE      the part MIME type/subtype
+#   AERC_FILENAME       the attachment filename (if any)
+#
+# The first filter which matches the email's mimetype will be used, so order
+# them from most to least specific.
+#
+# You can also match on non-mimetypes, by prefixing with the header to match
+# against (non-case-sensitive) and a comma, e.g. subject,text will match a
+# subject which contains "text". Use header,~regex to match against a regex.
