How to set up DMARC for ListManager in Valimail

Updated over a week ago

This article covers the SPF and DKIM authentication processes for ListManager and how they are managed in Valimail. While only one of the two authentication methods is required for an email to pass DMARC, our recommendation is to configure both whenever possible.

Configuring DKIM authentication for your ListManager emails

1. Select the options you want in the DKIM/DomainKeys tab for a specific site. This includes generating public and private keys, which are essential to the operation of DKIM/DomainKeys.

2. Create and publish the domain TXT records (this includes publishing the public key to DNS).

3. When you send email, the private key generates a digital signature of the message.

4. The DKIM/DomainKeys-enabled receiving server extracts the digital signature and claimed From: or Sender: domain from the headers.

5. The receiving server fetches the public key from DNS and checks it against the private key. If it's a match, this proves that the claimed From: or Sender: domain is accurate and the headers and content were not altered.
