Having difficulty with mail routing. I have Acronis backup installed on our network clients and am trying to get the backup status email message to send to my Notes account. When the status email hits the Domino server it is presented as originating from machine_name.domain.com and because this address cannot be verified using reverse DNS lookup, the email is rejected. Without compromising the effective anti-spam settings in the server document, how to configure Domino to relay these emails to my Notes client.
Subject: PTR records
Ben,
After getting back to work I checked in our internal DNS and there are already both A and PTR records which were produced by our internal DNS server. Our public IP does have A, MX and PTR records. Is there somewhere else that you may be referring to?
Subject: Perhaps
Point the backup software to route emails to a internal smtp hub that does not do the reverse lookup. Any domino server with the smtp task loaded can function as the hub
Subject: .
Check the Server mail configuration, SMTP Inbound, mail relay exception list.
Subject: PTR
If you want to keep that setting to “Verify connecting hostname in DNS” (and you should!) then the solution is to add the PTR in your DNS zone for that subnet. All networks should have an accurately populated reverse lookup zone. Your DNS Server administrator will have to do this for you, if you are not said administrator. For example if your acronis server’s IP address is 192.168.1.10, and the hostname is machine_name.domain.com, you need this record:
10.1.168.192.in-addr.arpa. IN PTR machine_name.domain.com

So for each client that runs the Acronis backup, they hane to have a PTR record in DNS? The Acronis software is a standalone package that isn’t controlled by a central server. But, if all it takes is a PTR to each client machine on the network, that should be easy enough.
