WebHostForASP.NET supports the ability to publish SPF records for domain name(s) using our name servers. SPF records are published by entering the SPF policy as a DNS TXT record.
By default we do not publish SPF records for our users. If you desire to add an SPF record for your domain name(s) you can use the SPF policy wizard located at: www.openspf.org/wizard.html. This wizard will ask you questions about how you want your SPF policy to operate.
For more information on SPF (Sender Policy Framework) please visit the SPF web site at http://www.openspf.org.
Note that we do not officially support SPF records. Should you make updates to the TXT records, you do so at their own risk.
