Which methods can be used to bypass Spam Scanning?

The correct approach to bypass spam scanning is to utilize methods that directly manipulate how emails are processed through a spam policy. Creating a new Spam Scanning Policy with the action "Tag Headers" achieves this goal by ensuring that emails from specified sources can be marked or tagged, effectively allowing safe handling without completely bypassing necessary scanning mechanisms. By tagging headers, whether for tracking or informational purposes, you can distinguish these emails while still having them scanned, hence offering a streamlined method to manage legitimate communications without them being flagged as spam.

Utilizing actions that adjust how emails are perceived and processed allows for more control over incoming emails while adhering to best practices of email security. Other methods may involve allowing certain senders but do not necessarily bypass spam scanning in the nuanced way that tagging headers will, as it retains the ability to monitor and manage incoming traffic efficiently.
