APOP Support APOP is a part of the POP3 protocol standard.
Many systems use it for obvious security reasons.
Although Eudora supports this protocol, OE does not at this time. Instead, OE supports Secure Password Authentication, which is the password authentication protocol that MSN employs. Well, OE now decodes BinHex, but it still does not offer a BinHex encoding option. The reason is that while BinHex is an older encoding technology, it is is very popular with Macs. BinHex encoding would enable OE users to send to Mac users whose mail clients require BinHex encoded messages.
