Yes, by having the policy service return a 4XX response. Postfix will do whatever the policy service asks. Your question is perhaps about those policy services, rather than Postfix per-se. Note that you SHOULD NOT ultimately refuse email on SPF softfail, but greylisting would be OK, if you find it meets your needs. -- Viktor.
