How to use the group feature to encrypt content to multiple public keys by using a single address

The group feature is relevant to companies or groups looking to encrypt content with several public keys of the group members while using a single address in the process.

To enable this feature

1. close all gpg applications and Mail.app
   
2. open finder, press Shift Cmd G (⇧⌘G), paste '~/.gnupg/gpg.conf' without the ' and click Go
   
3. open gpg.conf with TextEdit
   
4. add the following line at the end of the file

    group staff@mywork.com = fingerprint1 fingerprint2 fingerprints

Whenever you now write to staff@mywork.com the mail will be encrypted with all the public keys you added with their fingerprints.
