Comment:
Good point, RFC 5322 addresses complicate this setup quite a bit. For example, my assumption was that `Alternate-Mailboxes` just contains the mail address but that's not necessarily the case, right? If so, it would probably make sense to modify `grepmine` in a way that it operates only on the mail address part and later map that address to the display name using a different function? Is there already any tool for extracting the display-name/mail-address part of an [RFC 5322 address](https://tools.ietf.org/html/rfc5322#section-3.4)?
