Stef,
Just looking at the output, my immediate thought was "this is base64
encoded". That would match if it works in an email reader as a base64
encoded attachment.
I don't have the time to go through 300+ LOC to try to figure out what
you code is doing, but when sending as either XML or HTML, you need to
first base64_decode() the text. Once you've done that, apply
htmlentities() to the string to encode the HTML entities. Then send it
to the RSS or HTML feed.
