Set up an SPF record for your domain and make sure its valid by testing it with a validation tool. SPF references ============== <http://www.openspf.org> provides an overview, documentation and SPF record builder wizards. <http://www.kitterman.com/spf/validate.html> has test tools to validate your SPF record after its built and again when it has been installed.
