Have you checked incoming mail from domains that actually contain SPF DNS records? It won't work for all mail unless the senders domain has an SPF record and they do, or not, send out via the authorized mailserver IP. Even so, the "TXT" record (usually TXT, could be SPF) has to end with "-all" to force a hard fail.
