Problem: You are sending a mail to a colleague "Peter Meyer" and while entering "Peter M" auto completion suggests 2 or 3 addresses from history. Unfortunately, you happen to choose the one and only address that had beend canceled meanwhile and your recipient will never get your mail. 

Solution: Activley decline the old address as soon as you are told it has been abandoned: Context menu: mark as invalid. The email address gets to the blacklisted recipients' list. Now you will be warned when you try to send a mail to the old address. It will occur red (or not at all) when you use auto completion from history.

Corrolar: This way you could also avoid responding to spam senders or phishers that ask you to send them a new password...
