MIME (Multipurpose Internet Mail Extensions) is an extension of Internet e-mail message format. Among other things, it defines a standard way to attach files to an email message.
The file type identification system used by MIME, MIME types, is also used by a number of other formats and protocols, such as HTTP.

[edit] Format
A MIME-compliant message is identified by the presence of a "MIME-Version" message header. The other headers used by MIME begin with "Content-". (This applies to the top level of an e-mail message. If MIME content is embedded in another format such as S/MIME, it may not require a MIME-Version header.)
Since MIME data is usually found as part of a message (as stored or transmitted by various means) rather than as a standalone file, it usually doesn't have a file extension. MIME headers or MIME-encoded messages saved for archiving or as example files might sometimes have a .mime extension.
