If you already use amavisd-new for DKIM verification, then use a custom hook that, conditional on a verified DKIM signature, does the VBR checks and lookups (using Net::DNS, perhaps). If you choose to go this route, please move the discussion to the amavisd-new mailing list. -- Sahil Tandon <sa...@freebsd.org>
