What must be identical for two emails to be considered duplicates?

For two emails to be considered duplicates, they must share key characteristics that indicate they are identical in content, context, and delivery. The most critical factors in determining duplication are the recipient, the attachment, and the Message Body Hash.

The recipient ensures that the email was sent to the same person or group, establishing the potential for the two emails to serve the same purpose. The attachment is vital because duplicates often include the same files or documents; without matching attachments, the emails may not serve the same function or convey identical information. The Message Body Hash provides a digital fingerprint of the email’s content, ensuring that there are no alterations in the text of the email itself. If the hash values are identical, it confirms that the body of the emails has not changed.

This combination of parameters guarantees a robust definition of what constitutes a duplicate email, ensuring that the nuances of content and context are preserved across both communications. The interplay of these elements helps manage and process email data effectively, particularly in legal or compliance contexts. Other options may include elements that are not as fundamental to establishing true duplication or may focus on aspects that can vary among emails while still retaining the same essential communication.
