The default action will be to accept mail, if one of the rbl servers goes down. If you have a high-enough mail volume you can sign Vix' indemnification agreement and they'll let you stealth-zone xfer the rbl zone so you can query your local server. This makes a huge speed difference if you do large volumes of mail. You can also subscribe via BGP, if you have anything that speaks it.
