Summary: Mails in list always show up with name from mail's header, independent of whether sender is in address book or not. 

Steps to Reproduce: Receive mail from contact in address book, while mail has header with bogus sender's name field.

Expected Results: The list of mails shows mail with name replaced by the address book entry's name.

Actual Results: The bogus name shows up.

Regression: Use lookup method used in mail view for list as well.

Notes: Address book details show up correctly in mail / conversation view.
This behavior is present since a long time, and is present on both, iOS and OSX.
While this might be intended, it seems to be better to use address book entries, as that might prevent spoofing (i.e. A sending B a mail with name C in header. B thinks mail is valid mail from C, but includes bad data from A.), therefore might also be a security issue.

Also, some clients do not include a correct name, a shortened name or different name than the user wants to show. (e.g, "W.Butler" instead of "William Butler", or "bloerwald@googlem..." instead of "Bernd Lörwald").

Attached is a screenshot with a list to show how ugly it might look. All senders have an address book entry there, as indicated by the picture available.
