We have a nice feature for catching wide-open SPF record:
        racl blacklist spf self
will reject message if your own IP is in the SPF range for the domain of
the message sender. 

Apart from that, I think SPF can be useful to whitelist yahoo's mail
farms and other big providers, but should not be used blindly. In fact
it woud be nice to have a DNS reverse white list of legitimate SPF
enabled domains.
