No, it doesn't. Postfix may convert 8bit mail into 7bit quoted-printable,
depending on whether disable_mime_output_conversion is yes or no,
and whether a down-stream SMTP receiver anounces 8BITMIME support.
Postfix does not convert 7bit mail into quoted-printable. That is
how it has worked since 2002.
Please solve the right problem.
