Re: MIME messages without MIME-Version header

> How to handle MIME (-like) messages without the MIME-version header field ?
Here is a excerpt from RFC 2045 that addresses your concern.

In the absence of a MIME-Version field, a receiving mail user agent
   (whether conforming to MIME requirements or not) may optionally
   choose to interpret the body of the message according to local
   conventions.
