Google’s new sender guidelines, ARC or Authenticated Received Chain is now a part of their latest requirements starting February . ARC secures email authentication information in situations where an email passes through multiple servers – thereby working as an additional layer of protection. Google ARC – Staying One Step Ahead of SPF and DKIM SPF and DKIM email authentication protocols are effective measures in ensuring that messages sent from your domain are verified before they reach your client’s inbox.
However, they are not perfect. SPF is ineffective Job Function Email List during email forwarding SPF verifies email messages against an authorized list of IP addresses. During email forwarding, the email passes through an intermediate server whose IP may not be included in the sender’s SPF list. This leads to unwanted SPF failures even for legitimate emails. DKIM isn’t always the saviour DKIM adds digital signatures to your emails which can be encrypted using a public key to verify the source and authenticity of the message.
To do so, DKIM uses a hash value that is generated using the email header and body. However, during email forwarding scenarios, additional elements like custom footers or extended subject lines can be added to the email – invalidating DKIM. Google Recommends Adding ARC Headers to Outgoing Emails Email headers and message content get altered during email forwarding, due to which SPF and DKIM fail for the email as a result of unsuccessful verification. ng MTA applies ARC for the email, three additional ARC headers are applied to.
