Well I finally found an answer on my own, searching the web, here:
Basically I had to change settings in GMail.
But still can't get the AOL account to do the same thing or figure how to change it from IMAP to POP3.
Found an answer to the AOL account problem. The new versions of mail do not have a checkbox for "automatically setup account" so it can not be "unchecked."
What you have to do is hold the OPTION key when creating the account and you can then choose POP or IMAP (or Exchange, etc.) to set up the account.
