still pounding on email

Went through over 150 emails today, testing the new email processing code. As a side benifit, I'll note that I had NO threading problems. 1 update or many queries is working very well now, thankyou. I get a wealth of emails at work and all my discarded emails make for great test data.

I've now got email header retention to the barest minimum. Also, the code is a whole lot cleaner. And that's good, 'cause I still have a few things I want to do, like promoting text/plain content.

I still very much need to change gears and write some slides. Perhaps in another week, but not too much longer than that, I can get started.
