When I went to forward an email and hit "send" to pick up contacts I wanted to send to I found quite a few emails addresses I have no idea who they are.  When I go to "contacts" I can not find these mystery emails only when I sending an email and pull down contacts in "send"  How do I eleminate these mystery emails?
Thank you
