Don't be that pessimistic. The MIME-Tools and the above sub do a great job for me separating text and non-text MIME components. As long as the mailer that sent the mail has ever heard about the relevant RFCs it is easy to handle.

If you don't believe, have a look at this webmailer (in German, but guessable) using the above sub.

For the fun surprises, notice the recursive call of that sub.
