Mime: multi-purpose internet mail extensions

Introduction to MIME MIME (Multipurpose Internet Mail Extensions) is a standard which was proposed by Bell Communications in 1991 in order to expand upon the limited capabilities of email, and in particular to allow documents (such as images, sound, and text) to be inserted in a message. It was originally defined by RFCs 1341 and 1342 in June 1992. Using headers, MIME describes the type of message content and the encoding used.
