If a user has many Relay IDs and happens to get emails which for some reason are not easily identifiable from the content as to which account sent them, then it would be useful if the information in the forwarding header also included the information from the Account note field which was provided when the ID was created.
Thanks for the feedback. Unfortunately - or fortunately? - the account note for the ID is saved client-side in the add-on so that Mozilla never has a record of where you created an alias. This means we don't have the account note in our server where we generate the forwarding header.
