 What would be obscenely useful is if dccifd could speak to postfix as a
content filter.

http://www.postfix.org/CONTENT_INSPECTION_README.html explains how
Postfix deal with content filtering. I'm a big fan of external,
medium-weight, real-time, even though Mr. Venema cautions against it,
simply because I can refuse the transaction without queuing the message
(even though you have to get the whole message to do a checksumming, I
know). YMMV.

If you did implement this, I'd be one of the first to switch to it. I'm
currently using dcc out of procmail, which I hate, as it doesn't
interface with my vdomain setup; only local users get the benefit of dcc...
