Can DNS policies be configured to bypass spam checks if the sender is on a permitted or Auto-Allow list?

In the context of email security and the functioning of DNS policies within Mimecast, configuring these policies to bypass spam checks based on a sender being on a permitted or Auto-Allow list is indeed not an option.

The fundamental role of DNS policies is to enhance security by assessing incoming email traffic against various criteria, including sender reputation. While being on a permitted or Auto-Allow list ensures that certain senders are generally treated favorably, it does not mean that bypassing spam checks will automatically take place through DNS policies. The integrity and security provided by continuously evaluating threats necessitates that all incoming email undergoes appropriate spam checks, regardless of senders' lists.

This framework helps maintain robust email security, ensuring that even trusted sources are analyzed for potential risks without compromising the overall defense mechanism. Thus, the answer reflects a core principle of email security management: the importance of thorough, automated checks to safeguard against spam and other malicious content, regardless of sender status.
