I assume your dovecot runs on some kind of *nix so there should be some
sort of netfilter available which you can put in front of your listening

It might be also an option to create some kind of "hooks" in dovecot
that can be used to connect to a DNSBL checker - so configuration can
happen outside of dovecot.
