Your input is NOT PROPERLY FORMATTED.
Your original message does not have whitespace at the beginning
of the second part of the Content-Type: header. Instead it has ".".
Your original message violates RFC 5322:
1) RFC 5322: Multi-line message headers must have whitespace at the
beginning of the second etc. line.
Your original message has "." at the beginning of a line, but your
SMTP client does not prepend "." as required by RFC RFC 5321.
Your SMTP client violates RFC 5231:
2) RFC 5321: The SMTP client MUST prepend "." to lines that start
with ".". The SMTP server MUST remove "." at the beginning of
a line.
