Ok, I want to set up real-time blackholing on a mail server running sendmail 8.9.3. My major concern is what will happen if one of the lookup hosts (e.g. rbl.maps.vix.com) suddenly becomes unavailable (either because our network goes down, or the lookup host goes down). Does anyone know? Will it time out (good) or will my server stop delivering mail until it can see the lookup host again (bad)? I couldn't find any info either way and I don't feel like parsing the code at the moment :) Any info would be greatly appreciated.
