Mail.app without adding to Address book

Posted by macboer on March 19, 2012 03:01 am 0

This is sort of difficult to explain but I'll try:

When I get an email from someone and I want to email that person without "replying." How do I get the address to autocomplete?

Do I HAVE TO add it to Address Book manually before it will be recognized by mail.app?

Thanks for your help.
