DKIM(recommended)

This article covers the SPF and DKIM authentication processes for Sophos Email Security 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 Sophos Email Security emails

1. Go to Global Settings -> Domains settings/status and click on the domain you want to add a DKIM key to.

2. Click Add key.

3. Copy the DKIM information that is generated automatically and use it to create a DNS TXT record for your domain.

Important: If you manage DKIM in Valimail for your domain, you will need to add the TXT DKIM key on your domain's Configuration page in Valimail Enforce.

4. Once your DNS TXT record has been published, click on Test record to check that your DNS TXT record matches the information in Sophos Email.

5. Activate the DKIM key then click Save.
