Our mail server employs SPF (Sender Policy Framework) as its authentication method.
This protocol, which is one of a number of different authentication records, verifies that emails are sent only from authorized senders, ensuring that messages from our mail server are securely delivered. SPF plays a crucial role in confirming email authenticity.
However, DKIM and DMARC may be required when connecting to an external service. In such cases, you will need to request the necessary records from your external service provider and add them to your DNS settings as a TXT record.
