I just traded in Mail.app for Sparrow and want to clear up some space on my hard drive. Is it safe to remove the
~/Library/Mail/V2/IMAP-[mailbox] folders for any mail accounts that I have removed from Mail.app?
EDIT: In response to the two "if by safe I assume" answers. I meant both "won't break Mail if I open it again and re-enable those accounts." and "won't delete the messages on the IMAP server"
