IMAP4 is being used to serve rich media content in environments that extend beyond traditional text-based e-mail. One example is a cellular telephone that can retrieve and send MIME-encoded audio data through IMAP4. While this type of content can be exchanged natively using IMAP4, some applications will work better if the message content can be manipulated using schemes external to the IMAP4 connection. In our cellular telephone example, it might be preferable for the telephone client to retrieve the audio data using RTSP. This specifications defines a mechanism for an IMAP4 client to request message content from a server through an external scheme.
