Public int getType() missing Legal value: RFC822 Text?

As far as I can see public int getType() is missing Legal value “RFC822 Text”. This happens when a Lotus Notes inbox database receives an external email (internet email), the message is MIME encoded and the fields receive encoded values (i.e.:From, SendTo, Subject, etc). Would you know if there is any updates/work arounds for this issue?
