spf

We have configured a SMTP server on IIS. We have not configured any SPF rule. Some emails are going straight to the badmail folder. Most of them have this error message:

Address does not pass the Sender Policy Framework

Is there any way to disable that? I know this is insecure and spammers could use it to send spam, but I really need it to be disabled for now until I have configured and tested the SPF correctly.
