Not really. The MIME type is obtained directly from a Content-Type
header or sub-header field of each mail part.

The file(1) utility is called without its -i option. The resulting
string is mapped through @map_full_type_to_short_type_re to obtain
a file extension.  MIME type as checked by banning rules does not
come from the file(1) utility.
