If you're using the Thunderbird news reader, typing Cntl-U will
show the full source of the message.
This is perfectly normal for emails and such. They are
multipart/alternative MIME messages which pack different versions
of the same message together and your client picks its preferred
one to show you.
It is kinda useless because the html version adds zero value, but
the text version is still there to so your client should just
ignore it.
