Yes, it was a shot in the dark replacing 2.1.5 Srubber with a 2.1.9
There are a number of errors in the logfile  e.g.

Nov 23 03:05:27 2008 (1800) SHUNTING:

Yes. Grant Taylor mentioned this. He made reference to format=flow being 
the go, rather that quoted=printable. I confess it's something I don't 
understand. I had thought f=f was something the email client decided.

Yes. I saw that also, I was pretending not to. ;-)
