It would be good if YAM used an HTML mui custom class to automatically show HTML emails properly. Yes HTML in emails is crap, but it would be nice to see them without messing about.
There is a very good HTML class written by Alan Odgaard(sp?) which could probably be used. There would be an option to view HTML files automatically, which would use the custom class to display the email if HTML was detected. I'm sure this would be fairly easy to implement.
