This reminds me of a concern that was raised about U Wash IMAP and storage of mail in unix home directories. In that setup IMAP access is based on unix file system permissions, and IMAP will open files that are not mail files if the user has unix file permissions to open them-- including various system files. This always struck me as a bogus concern since the user could also telnet in and see the same files! The protocol itself is no less secure than POP. I don't understand why POP is still around.
