Sophos supports both SPF and DKIM. To ensure that your outgoing emails routed through Sophos Gateways pass DMARC checks and are successfully delivered to recipients, you need to properly configure SPF and DKIM for the Sophos Security Gateway.
To set up SPF and DKIM, you will need to contact Sophos Support, as they will provide the required configuration details and guidance specific to your environment.
