X-Warning: We ASSUME it is less harmful to add the MIME headers, and convert the text to Quoted-Printable, than not to do so, and to strip the message to 7-bits.. (RFC 1428 Appendix A) X-Warning: We don't know what character set the user used, thus we had to write these MIME-headers with our local system default value.
