I've been looking at flushaddr to solve this problem. The notation would 
look like:
acl blacklist dnsrbl "PSU BLACKLIST" msg "You are on the PSU blacklist. 
Please  go away" flushaddr

Here is some info from the man page found in the 4.4.3 source:

  flushaddr
                If a message matches the rule, any entry in the
                greylist or autowhite databases matching the sender IP
                is removed. Used with a DNSRBL blacklist ACL, it is
                useful for freeing the database from entries set up by
                a machine which is known to be a spammer. Example:

   racl blacklist dnsrbl "known-spammer" flushaddr

I am testing:
whitelist
dnsrbl black
greylist
default whitelist
