We have a backup MX running offsite that handles store/forward for email when our primary network is unreachable.
I'm wondering if there's a way to whitelist SOME things, but not others (we could on our last filter). We'd like to ignore SPF from our backup MX server (since it is not for sending email out to the world, so doesn't fit a true SPF scenario), but still do other spam checks. Ideally, we'd like to be able to pick and choose which options are checked for different sources and/or destinations... say... ignore SPF from our backup MX, or ignore rDNS for a specific delivery domain, etc -- much as we had with our last 2 email filters.
Is this something that can be done with Proxmox? Or is this something we'll need to look elsewhere for?
