SPF検査はspamを拒否するためのものではなく、正常なメールを受信するためのものです。

spfbehavior
    Use this to turn on SPF checking. The default value is 0 (off).
    You can specify a value between 0 and 6:

        0: Never do SPF lookups, don't create Received-SPF headers
        1: Only create Received-SPF headers, never block
        2: Use temporary errors when you have DNS lookup problems
        3: Reject mails when SPF resolves to fail (deny)
        4: Reject mails when SPF resolves to softfail
        5: Reject mails when SPF resolves to neutral
        6: Reject mails when SPF does not resolve to pass

    Values bigger than 3 are strongly discouraged, you probably want to go with 2 or 3. 

Important: This setting can be overridden using the environment variable SPFBEHAVIOR,
e.g. from tcpserver rules.
    Note: If RELAYCLIENT is set, SPF checks won't run at all.
    (This also includes SMTP-AUTH and similar patches)
