The normal MIME based mail format with all it's pain in header encoding, multi part bodies, language and encoding annotations etc. EDIT: Note to be confused with Media-Types which are a (very) small part of the MIME specification and are sometimes called MIME Types. Due to their use in http they got their own spec later on (and are also redefined in the HTTP spec instead of referring to the mime spec, funnily their re-definition in the HTTP spec doesn't 100% match the specification in the MIME spec, luckily only in "don't do this every" parts).
