I've previously sent emails from my iPhone to a particular address. I didn't add the address to my contact list, as I didn't intend to send them many emails, and always just replied to theirs.
Now, whenever I compose a new email on my iPhone, when I start typing somebody else's name in the "to" box, this old email address keeps coming up on the list of names to pick from, even though they are NOT in my contacts list.
It seems that the iPhone keeps a list of email addresses previously emailed to or from.
How can I clear this list out, without having to do a full reset or restore on my iPhone?
