Yes. It looks extremely cool. Vernon Schryver (the author) has been
marketing it saying installation takes only a few minutes - while this is
true once you've read and understood the documentation, that part takes a
little more time.

I am currently working on integrating DCC with qmail and procmail via the
'dccproc' procmail interface to dcc. I have some ideas about integrating it
with qmail; probably via a qmail-local wrapper (dccproc adds an X-DCC header
to the mail). I'm configuring my spamtraps with
| dccproc -t many -o /dev/null
in dot-qmail(5); this creates a nice line in my qmail-send log with the
report dccproc made.

DCC wasn't publicly available until July 12th. There has been some activity
on the DCC mailing list - but not much.
