Hank, A couple of weeks ago you and Tony posted patches to make sb_filter obey the notate_to and notate_subject options. I've finally applied a modified version of them, that respects both of those options. I've committed it to the head, so it may not be in the next bugfix release, but will be in the next feature release.
I by no means mean to nitpick, but it would be very nice to see the Prob score in the Subject as well.
I didn't do this, partly because none of the other header-modifying spambayes applications does it, and partly because it made the To / Subject very messy looking. And I find that the scores get less interesting over time - they're fun to look at at first, and useful when debugging, but day to day I don't look at them. YMMV. 8-)
So far, I am VERY happy with how this filter is performing. I am now rolling it out to the rest of my clients, and so far it is well received.
Hope its still going well? -- Richie Hindle richie@entrian.com
