> I would need some advice on SPF whitelisting. The situation is that I use backup mx host which is out of my control and I cannot believe it is checking DKIM/DMARC by itself and I need to check it on the primary mx host. So I want to whitelist the backup mx's IP address to stop SPF failing when receiving messages through it to my primary mx host. But I do not want to use IgnoreHosts option since it will stop DKIM checking for messages received through the backup mx host.

Hello Marek,
I'm not aware skipping SPF checks only is possible with opendmarc.
