I received the two attached messages sent from a web-based e-mail program.  They
are both HTML messages but are displayed as plain text in Mozilla (OE displays
them fine).  "View Message As" is set to "original HTML".   All other HTML
messages display fine.

both messages use multipart/alternative. RFC says that the email client should
show the last part its able to display. Also, rcf says that part should be
placed in the order of the poorest to the richest content.

The sample message put first the html part and then the plain text one. Mozilla
correctly show the last one it can display: the plain text one. This is a
problem with the email client who generated the message and not Mozilla.

Now, do we want to break the rules to support those lazy mta? That could cause
regression with other MTA!
