N2Net relies on Sender Policy Framework (SPF) and DomainKeys Identified Mail (DKIM) to help protect the authenticity of email sent from domains hosted on our email platform.

Sender Policy Framework (SPF)

SPF uses DNS records to define what IP addresses are allowed to send email for a domain.  This means that if your email is hosted by N2Net, you need to be sure that you are using the proper N2Net outbound (SMTP) email server to send all outbound mail.  If you send email using another SMTP server, the SPF will mostly likely cause the message to be marked as spam or rejected by the recipient.

DomainKeys Identified Mail (DKIM)

DKIM also uses DNS records and a encryption based digital signature to further verify that a message was sent through the proper SMTP server.  As with SPF, please make sure that you are using the proper outbound SMTP email server for your email domain.
