We have clustered Domino 8.5 servers. Server2 rejects all email when the DNS Blacklist is set to “Log and Reject”, but Server1 works as expected. On Server2, the DNS on the Windows server itself appears to be working correctly and we can ping the blacklists by name. We have verified that both servers have the same SMTP Inbound Controls. Any ideas, anyone?

Check your Server configuration, more specific your Router/Smtp setting. Match it to the your server that is working.

We did that. Everything looks identical.
Subject: Blacklisting
You might need to let your cluster to be able to relay between then. I never seen this problem and I have my SMTP server cluster as well…
Subject: Same problem here
New server installation, configuration is identical to others servers I manage, but this new server rejects every mail saying that the IP of the incoming host is blacklisted.
I checked the blacklist site and look for that IP, and it’s not really blacklisted …
