Making that distinction, that even though most people are going to
regard most bulk mail as spam, dcc is not a spam detector, injects
sanity to the thread. We were drifting toward viewing dcc as just
another spam detector. Reliably diverting bulk to a bulk folder
at the user level mail reader with no false positives is a solid
feature.

Conceivably spamassassin might be relieved of further work at
the point dcc yields a Bulk Poz status header, but clamav ought
still to be run in a less than perfect world, just in case anybody
actually reads the stuff.

What no false-positive bulk markup with no false positives on
obscure mail list servers translates to for me is "guilt-free kill,
safe to ignore, safe to delete the whole Bulk folder periodically".
100% is hard to find even in an incremental building block.
