If I make a typo in an email address and send it, the next time I go to send an email, that same typo shows up as a suggested email for that person... Similar issue - my friend changes their email address, I change it in my contacts. But, the old email address still shows up as a suggestion when composing new emails... How can I purge these "collected" email addresses, which don't come from my contacts? Can I do this on an individual basis? And/or all-at-once?
