Removing an Email account
WARNING: Removing an account in MacMail will permanently delete its mailboxes, messages, notes, and to do items. If you want to keep those, be sure to copy them to an On My Mac mailbox before deleting the account.
Exchange, IMAP, and MobileMe accounts store their mailboxes and messages on the server; deleting these account types in Mail will not permanently delete messages from the server. However, if you are not completely certain that your account is one of those types, be sure to copy the mailboxes and messages you want to keep into an On My Mac mailbox, or save individual messages manually by selecting them and choosing Save As from the File menu.
