[Mimedefang] Problem with MIME::Tools and base64 encoded message/rfc822 attachements

[Faraz Vahabzadeh]

Dianne is correct!

I guess the sample file is not a good one. Either the Content-Type has 
to change to "text/plain" or if you are really dealing with such badly 
constructed messages in real life then as the man page for Mime::Parser 
suggests just turn off nested message extraction ($parser->extract_nested_messages(0);)
which treats that particular mime part as "text/plain".

And adding MIME::Tools->debugging(1); can help a lot debugging your 
program.

Cheers,
