*
* Notes on content-transfer-encoding.
*
* "7bit" means short lines of US-ASCII.
* "8bit" means short lines of octets with (possibly) the high-order bit set.
* "binary" means lines are not necessarily short enough for SMTP
* transport, and non-ASCII characters may be present.
*
* Only "7bit", "quoted-printable", and "base64" are universally safe
* for transport via e-mail. (Though many MTAs can/will be configured to
* automatically convert encodings to a safe type if they receive
* mail encoded in '8bit' and/or 'binary' encodings.
