Which property in the MailMessage class is used to get the Date of an email?

In the MailMessage class, the property used to retrieve the date of an email is the Headers("Date"). This property specifically accesses the "Date" header in the email's metadata, which provides the timestamp when the email was sent. This is crucial for applications that need to sort, display, or manage emails based on their arrival times.

The other options, while related to email headers, do not serve the purpose of obtaining the date. The "Subject" header provides the title or topic of the email, the "From" header indicates the sender's email address, and the "To" header specifies the recipient's address. None of these headers contain the date information, making the "Date" header the appropriate choice for identifying when an email was sent.
