sender Policy Framework is a framework for publishing information through DNS describing a list of ip addresses allowed to send email from a specific domain. This wizard is designed to help email admins to construct what that information should be.Most domains send outbound mail through a relatively small number of servers. Domains should describe that set of servers in an SPF record in their DNS. Internet email receivers can then reject forged messages which don39;t come from an envelope sender domain39;s approved servers. This wizard helps domain owners identify all the servers which could be expected to send mail from their domain.
