What SPF_NONE means
The envelope sender's domain publishes no SPF record at all.
The rule's description in SpamAssassin: “SPF: sender does not publish an SPF Record”
How to fix it
Publish a TXT record on the domain, for example v=spf1 include:_spf.google.com ~all, listing every service that sends mail for it. Gmail and Yahoo require SPF or DKIM from all senders.
This rule adds almost nothing to the score by itself. It matters only together with other rules.
