Where can I find my contact list in mail
In reply to an older post...
With the cursor in one of the address fields (To:, Cc:, or Bcc:) you should see a blue circle with a "+" sign. Clicking this blue circle should pop-up a view of your contacts, including any groups, or smart groups you may have created.
If you know the name of a group, or smart group, you can begin typing the group name in the address field and select the entire group from the pop-up.
