Note that their license is not considered a free software license, mainly
because Commtouch patents cover the DCC technology, and Rhyolite has to
send them royalties for commercial use:
* This agreement is not applicable to any entity which sells anti-spam
* solutions to others or provides an anti-spam solution as part of a
* security solution sold to other entities, or to a private network
* which employs the DCC or uses data provided by operation of the DCC
* but does not provide corresponding data to other users.
That being said, I have read the DCC source code and it's a pretty cool
collection of hacks. It's very, very old, but amazingly functional even
today.
