Best practices on logical separation of abuse@ vs dmca@ role inboxes

If you were setting up something new from a clean sheet of paper design - do you consider it appropriate to have an abuse role inbox that's dedicated to actual network abuse issues (security problems, DDoS, IP hijacks, misbehavior of downstream customers, etc), and keep that separate from DMCA notifications? Automated sorting tools *can* pull things which match regexes for automatically-generated DMCA notifications out of an inbox and route them to the appropriate place. However, I'm pondering whether it's better to have an ISP's ARIN IP space whois entries state clearly that copyright violation type notices should go to a dedicated-purpose dmca@ispname inbox.
