Yes, configuring DKIM on your mail server is generally recommended to help prevent email spoofing and increase trust in your outgoing messages. Here is a technical description of the process:
DKIM (DomainKeys Identified Mail) works by adding a digital signature to outgoing messages that can be validated by receiving servers using a public key published in your domain’s DNS. To enable DKIM, you must generate a pair of cryptographic keys (a public key and a private key) on your mail server.
Next, you will need to publish the public key in a DNS TXT record associated with your domain. This requires modifying your DNS settings, either directly through your domain registrar or through a DNS management tool provided by your web hosting provider.
Finally, you will need to configure your mail server to sign outgoing messages with the private key. This can be done using an email server software and configuration file, which varies depending on the specific program you are using.
Once DKIM is enabled, messages sent from your domain will include a signature that can be verified by receiving servers, which can help prevent spam and phishing attempts.
