It would be extra nice if one day this stuff was configurable for your
installation, rather than having to patch the source. For instance, we add
X-Spam-score: and X-Spam-hits: headers and one day I'd like to add code to
display these in our web-interface. To keep the performance reasonable
though, I'll have to patch so that it caches these headers. Every extra
patch is annoying to have to maintain in the long run...
