Here is my SPF record, but sending email I get this in the header @ 86400 IN txt v=spf1 a mx ptr ~all Received-SPF: neutral (google.com: 75.126.62.147 is neither permitted nor denied by domain of gr******ardt@gmail.com) client-ip=75.126.62.147; Authentication-Results: mx.google.com; spf=neutral (google.com: 75.126.62.147 is neither permitted nor denied by domain of gr******ardt@gmail.com) smtp.mail=gr******ardt@gmail.com
Assuming that your ips is 75.126.62.147 then your spf record must be the following v=spf1 ip4:75.126.62.147 ~all or v=spf1 sportscardforum.com ~all
If you allow relayin then it is not a problem but if you dont then it is a problem but not related to spf.
