8 * different headers --- in particular it includes an "adler-32"

10 * checksum, and since not all PHP's have gzcompress(), we'll just
11 * stick with gzopen().

534 * Notes on content-transfer-encoding.
536 * "7bit" means short lines of US-ASCII.
537 * "8bit" means short lines of octets with (possibly) the high-order bit set.
538 * "binary" means lines are not necessarily short enough for SMTP
539 * transport, and non-ASCII characters may be present.
541 * Only "7bit", "quoted-printable", and "base64" are universally safe
542 * for transport via e-mail. (Though many MTAs can/will be configured to
543 * automatically convert encodings to a safe type if they receive
544 * mail encoded in '8bit' and/or 'binary' encodings.
