This module aims to show the recipients of an email in the email header, but the previous implementation was not suitable for internal notes.
When **logging an internal note** with tagged users and/or partners, those specific recipients should be displayed
as well as the document's followers subscribed to this message subtype.
When **sending an email**, the recipients should be the document's followers.
This is achieved by using the union of `mail.mail`'s `recipient_ids` and `notified_partner_ids`.
Added settings to customize notification and translations to important parts of the message.
