To authenticate your Web.com account and enhance the security of your email communication, it's crucial to configure SPF settings. SPF (Sender Policy Framework) helps prevent email spoofing by specifying which servers are allowed to send emails on behalf of your domain.
While DKIM (DomainKeys Identified Mail) is a highly effective method for email authentication, please note that Web.com currently does not support DKIM settings. Therefore, our recommendation for securing your email communication on Web.com primarily involves implementing SPF only.
