Electronic mail protocols are application layer protocols. Mail servers use SMTP to send and receive mail messages. User-level client mail applications use SMTP for sending messages to a mail server for relaying and use another protocol to receive messages: POP, IMAP or a proprietary system such as Microsoft Exchange or Lotus Notes/Domino. Electronic mail protocols are often combined with cryptographic protocols. Information related to such protocols (IMAPS, STARTTLS etc.) should also be submitted to this category.
