Mail::Encodings.decode_encode

Decodes or encodes a string as needed for either Base64 or QP encoding types in
the =?<encoding>?[QB]?<string>?=" format.

The output type needs to be :decode to decode the input string or :encode to
encode the input string.  The character set used for encoding will either be
the value of $KCODE for Ruby < 1.9 or the encoding on the string passed in.

On encoding, will only send out Base64 encoded strings.
