How to set up DMARC for Google Workspace in Valimail

Updated over a week ago
SPF(supported)
DKIM(recommended)

This article covers the SPF and DKIM authentication processes for Google Workspace 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 Google Workspace emails

Note: You need to signed into the Google Workspace console as a super administrator. More details here.

1. Sign in to your Google Admin console (at admin.google.com) with super administrator privileges.

2. Go to Apps -> Google Workspace -> Gmail.

3. Click Authenticate email.

4. In the Selected domain menu, select the domain where you want to set up DKIM.

5. Click the Generate New Record button.

6. In the Generate New Record box, select your DKIM key settings. We recommend you choose the 2048 key value.

Setting

Options

DKIM key bit length

2048—If your domain provider supports 2048-bit keys, select this option. Longer keys are more secure than shorter keys. If you previously used a 1024-bit key, you can switch to a 2048-bit key if your domain provider supports them. Read more about domain keys and TXT record limits.

1024—If your domain host doesn't support 2048-bit keys, select this option.

Prefix selector

The default selector prefix is google. We recommend you use the default.

If your domain already uses a DKIM key with the prefix google, enter a different prefix in this field. Read more about DKIM selectors.

7. At the bottom of the Generate new record box, click Generate. On the setting page, the text string beneath TXT record value changes to a new value and this message is displayed: DKIM authentication settings updated.

8. Copy the DKIM values shown in the Authenticate email window and publish the Google generated DKIM key in the Valimail Enforce platform.

9. After adding the DKIM TXT key record in Valimail Enforce, click on Start Authentication in your Google Workspace admin panel.

Enable SPF alignment Google Workspace for your domain

You may notice that Google Workspace emails are not authenticated via SPF, even after you have added Google Workspace to your domain's configuration. This is likely caused by Google Workspace not sending SPF aligned-mail and can be corrected by the service owner turn on SPF alignment for your domain in Google Workspace.
