[exim] dnslists - how to reject only if sender is in two or …

Hello, list

Now I have:
warn    message       = X-Local-Spam: ***SPAM*** $h_Subject
            hosts         = !+relay_from_hosts
            dnslists      = cbl.abuseat.org : sbl-xbl.spamhaus.org :
bl.spamcop.net

then in filters.conf I deliver the message to designated folder

I want to reject the message completely if sender is in two or more RBLs
and accept if
it hits only one.

Doable?

Thank you.
