Variable: mm-use-ultra-safe-encoding
mm-use-ultra-safe-encoding is a variable defined in mm-encode.el.gz.
Value
nil
Documentation
If non-nil, use encodings aimed at Procrustean bed survival.
This means that textual parts are encoded as quoted-printable if they contain lines longer than 76 characters or starting with "From " in the body. Non-7bit encodings (8bit, binary) are generally disallowed. This is to reduce the probability that a broken MTA or MDA changes the message.
This variable should never be set directly, but bound before a call to
mml-generate-mime or similar functions.
