MIME Content Type for BinHex Encoded Files
Patrik Fältström, D. Crocker, E. Fair · 1994
This memo describes the format to use when sending BinHex4.0 files via MIME [BORE93]. The format is compatible with existing mechanisms for distributing Macintosh files. Only when available software and/or user practice dictates, should this method be employed. It is recommended to use application/applefile [FALT94] for maximum interoperability.
