The milter's header-processing code is pretty simplistic. I just did a
couple tests sending 0-byte messages, and it couldn't even parse the
X-Spam-Report header out of the message, probably because it was the
very first header and the code checks for "\nHeader: ".
My guess is it crashed trying to process the body text, but I'm not
sure. I'll have to fix the header-processing bug first :)
