"=3D" is the encoded version of "=" for quoted-printable encoding. Since
"=" has a special meaning in quoted-printable it has to be escaped by
using "=3D".

So - if your mail body is sent as quoted-printable, all is OK - just
make sure, the Content-Transfer-Encoding header also contains
"quoted-printable".

Also see <https://www.ietf.org/rfc/rfc2045.txt> and
<http://en.wikipedia.org/wiki/Quoted-printable>.
