Just to let you know that I have installed a perl prefilter
to split the **subject line only** on lowercase to upper case 
transitions (and full stops as these also seem to be used for 
conjoining words).

There is a check in my .procmailrc file for such subject lines
and the filter is only invoked when a matching subject line is 
detected.

As the filter is only used when ConjoinedCaps are detected,
it does not impose much overhead.

Not sure how much difference it makes.
Don't think I have had another ConjoinedCaps spam 
since I made the change.
- so maybe my concern was misplaced.
