I'm having a problem with SPF soft fail detection for a particular domain that I cannot explain. Emails are being rejected for the domain because emails are being hit with the SPF_FAIL rule, but according to the SPF record, they should be hit with the SPF_SOFTFAIL rule.
The domain in question is nawilliams.com. This is the SPF record: "v=spf1 mx ptr ~all" I'm seeing other domains being hit with SPF_SOFTFAIL, so I am at a loss as to why this one isn't. What am I missing? I am using SpamAssassin 3.3.1 provided by Ubuntu 10.04. Neil
