Your original message looks like this:
> |Content-Type: multipart/alternative;
> |boundary="----_=_NextPart_001_01C9A2F0.A8C3BC75"
> |Subject: Another test

This is not a correctly formed message header. In particular,
the Content-Type: header is broken.
See RFC 5322 for creating multi-line message headers. Don't
write mail software without reading basic standards, please.
