One thing I always do on my MTAs that use DNSBls is only use zone transfers of blacklists on my DNS server. I currently use 7 DNSBls from Sendmail, only 2 commercial lists. That brings the total DNS queries for each message to around 10. Now I don't deal with tons of mail per day, compared to some people out there. Last count was around 45k per day. Still I think this is the only way to go for a reasonably sized mail system. Stalling sendmail processes waiting on my DNS server to say that such and such zone isn't available because the NS didn't respond is not an option IMHO. I've even considered adding RAM to my mail boxes and making them slaves for those blacklist zones. I don't think it would help. Our LAN is speedy enough to take a couple ms to get the answers back from the DNS server.
