Can the SPF plugin recognise overly permissive settings so they can trigger additional rules?
IOW it would be useful to be able to make a distinction between mail from correctly listed MX servers in a domain, e.g. "v=spf1 MX -all" and mail from a domain that is over permissive, e.g. "v=spf1 +all". My understanding is that both of these will trigger the SPF_PASS rule, which seems wrong. I'd suggest that any SPF record containing '+all' and possibly '?all' too, should trigger an SPF_PERMISSIVE rule rather than SPF_PASS so we can distinguish an authorised server in a tightly controlled domain from servers claiming to be part of a domain that doesn't give a damn.
