Sender authentication

There are two standards to check the sender’s identity: SPF and DKIM. RealSender offers both of them:

  • SPF declares which are the authorized smtp servers for a certain domain
  • DKIM digitally signs each message sent from a certain domain and its related smtp server
    All the informations used to check the DKIM signed messages, are saved and locked within the domain’s DNS settings
