[MM3-users] Archiving Display Email Signature in Plain-Text

The Archiving is still display Email Signature in Plain-Text after I configured filter content: No and convert html to plaintext: No in Alter Messages. And Markdown text in Archiving settings. In addition to that, I also configured HYPERKITTY_RENDER_INLINE_IMAGE = True in settings.py file

Where else should take a look into this? My email signature is from CodeTwo.

Thanks, Marin
