Using Evolution 3.28.1-2 (installed from the Ubuntu 18.04 repositories) and added my PGP key to one of my accounts. It works fine but Evolution inlines my PGP key instead of adding it as an attachment.
This works of course but confuses my colleagues since all mails start with the cryptic
-----BEGIN PGP SIGNED MESSAGE----- text.
Is there a way to tell Evolution to add the public key as an attachment instead? I though that was how it worked in the Evolution version I used in Ubuntu 17.10 but I might be mistaken.
