Hello and thank you for this tool.
It seems that gmail picks up an attachment "noname" and its the authentik logo png image while I have already changed the logo everywhere.
In the original mail I can see this at the end:
--===============8064252968654389452==
Content-Type: image/png
MIME-Version: 1.0
Content-Transfer-Encoding: base64
Content-ID: logo.png

--===============8064252968654389452==--

How can I remove the attachment or at least change the logo.png to my logo?

Thank you
