I've noticed that DCC_CHECK is flagging on tons of items that are
clearly not spam.  The most recent hit for me today was a release
announcement from the mariadb folks.  Overall, it's a trend I'm
routinely seeing where it is flagging a lot of email that clearly isn't
spam.  Are others who use DCC seeing similar issues?

that happens with all sort of shared hashs (Pyzor, Razor, Ixhash) while Pyzor has the most false positive rates and is caused by two problems:

* a ton of braindead idiots flagging their mail which they
  no longer want to receive as spam instead just unsubscribe

* bugs in the software while decide which parts of a message are
  used for the hashing up to genearte a hash for nothing after
  strip anything from a message
