MDaemon 11.x: Message Certification (VBR) in MDaemon
MDaemon 9.6 was the first commercial implementation of VBR ('Vouch by Reference'), an extension to Internet mail that is being created by the Domain Assurance Council which allows certification of messages by trusted providers. VBR involves adding an extra header to the outbound message which indicates that your domain fits the criteria for 'good email practices.'Until there are more reputation service providers providing this service, Alt-N Technologies will step into this role and provide certification services for the MDaemon community. To submit a request to have your domain's messages certified by Alt-N please visit http://www.altn.com/email-certification/signup/. Once you have signed up, you will need to configure MDaemon to use Alt-N Technologies as a certification provider.
