when secondary MX server forwards messages to primary MX, how can I
setup SPF policy to make them not breaking SPF?

its not clear if its outbound mx or inbound,
MX is inbound by definition.
Even the OP describes that it passes mail to the primary.
but postfix mynetworks
...have nothing to do with MX
should have backup mx ip on primary, so postscreen and check policy is
skipped for mails from internal networks
Postfix should skip SPF checking when receiving mail from backup MX, the
backup MX server should validate SPF instead.
While this can be achieved by configuring mynetworks and skipping SPF/policy
checks for mynetworks sources, it's different issue.
