   I think it unzips and then guesses the filetype of the unzipped file.
Guessing is a widely deploying trick in software, alas.
   Web headers are better in this regard as there are separate
Content-Type and Content-Encoding headers. In email, there is a
Content-Transfer-Encoding header but it has a different meaning - it is
either 8bit, or base64, or quoted-printable - it's the transfer encoding
*after* the file has been (g)zipped.
