Hi all,

defined extension_map in /etc/rspamd/local.d/mime_types.conf to avoid following line in E-Mail Header

X-Spamd-Result: default: False [0.80 / 15.00];

This is an excerpt from the raw E-Mail-Code:

Content-Type: application/x-unknown-content-type; name="Kastner.jpeg"
Content-Disposition: attachment; filename="Kastner.jpeg"
Content-Transfer-Encoding: base64

This is how i defined my extension_map:

extension_map = {

   jpeg = [






So, why does it not work, although the Content-Type matches?

best regards, Andi
