Not a bug really. More of a comment.

With a store set to send emails from only one domain, archived emails still have the from address as something else. Which just kind of means that the archive is not actually accurate.

So a 'tell-a-friend' email from [email protected] will appear in the archive as from [email protected] but actually be sent from [email protected].

Not a big deal but I think it would make more sense if the archive reflected the sent emails.
