How do I remove archived email addresses saved in the MacMail (v9.3) system for contacts that have changed their email address? For example, in the “To” field if you start typoing a person’s name, a previously used address will auto populate the field, but what if that address is not use any more? Is there any way to have this system reference to the old email address deleted? I’m using El Capitan (10.11.6) on a mid 2012 Macbook Pro. By the way, I could not find a way to send you a screen shot of the problem.
