Yes, that's safe, since any email coming in on was either
generated locally, or originally came from another IP (and has already
been processed).

Unfortunately, you can't do that :)  The libmilter API doesn't allow
you send a reject message back to the sender AND continue delivering
the mail.  You can do both, but it requires you to patch the sendmail
source and rebuild - savannah patch 714 does this.  So the current
behaviour with both flags is

score < required_hits : deliver normally
score between required_hits and -r value : tag
score >= -r value : reject

The only other way to do this would be to have spamass-milter reinject
the message into sendmail itself, which would add another Received:
header and complicate things (at minimum you would have to require -i to ensure that you don't get into a forwarding loop with
