- The MIME-headers should be in the headers only.
-
- Well, "my ideal" MTA would only analyse the headers of a message
- needed for routing (if at all), transfer everything without changing
- any bit (except adding "Received"-lines perhaps) and forward the
- message to next next MTA on the way to the receipient.
-
- It's the MUA's job to interpret the content of the message, only,
- but the MUA must know about the encoding used and stuff like that.
-
- RFC 821 explicitly forces you to cut the MSB, so SMTP MTAs fully
- conforming to RFC 821 will not be able to transfer binary or even
- 8bit data. Quoted-printables and base64 may be transmitted without
- any problems, but you'll have to tell your MUA manually to convert
- the message, if at all possible. It's like using uuencode/uudecode.
-
- What's your problem changing header lines? Maybe we can help you to
- do this somehow.
