So, the cPanel web hosting management console has a GnuPG Keys area, which allows you to create or import GPG/PGP keys. However, it doesn't seem that the server actually does anything with them once added to this area?Their documentation indicates Servers that use GnuPG keys encrypt outbound messages with a public key. Is there a way to configure a cPanel server to always sign outbound email messages with a given GnuPG key? Or is this feature of cPanel just a GnuPG Keyring (an easy way for you to find/reference your keys)?
Use GPG keys in cPanel?
