When you type an address in Mail, it helps you out by Autofilling recently used addresses. Start typing a name, and you can click the correct one on the list using your mouse (or use the arrow & tab keys on your keyboard).
But are you finding old, incorrect, and unknown addresses in the autofill? Here’s how to take names off the list:
- In the Mail program, go to Window > Previous Recipients. A window will pop up showing every address you’ve ever sent a message to.
- Click on any name you don’t want, and click on the Remove from List button.
- If the email belongs to someone in your address book but isn’t associated with their name, click on the Add to Address Book button.
I have repeatedly emptied the “previous recipients” file but Mail autocompletes with bad data (i.e. mismatched name/email address). My “Address Book” entries look okay; I don’t know where Mail is getting the information from but it is driving me nuts.
