Cannot verify senders' domain in DNS

We are running Domino R5 v5.0.8 on an AS/400 170. When I enable the Verify senders domain in DNS, I get messages in the log "Domain not found in DNS." So I assume it is doing its job. Unfortunately these are valid customers and we need their e-mail. What do they need to change or am I to just run with this option disabled?
I have tried this option myself and have not had good luck with it. I assume you turned it on to try to control inbound spam. A better way to go is to use a third-party mail blocker that supports the Realtime Blackhole List (RBL) or use Domino R6, which supports it natively.
