Which property of the MailMessage class in Visual Basic is used to retrieve the Date of an email?

The MailMessage class in Visual Basic provides several properties that allow you to interact with email messages effectively. To retrieve the date an email was sent, the "Headers" property is utilized, specifically with the key "Date." This allows the extraction of raw header information associated with the email, including the date when the email was dispatched.

Using Headers("Date") is straightforward as it directly references the email's metadata stored in the headers. The "Date" header is generally included with all email messages, ensuring its reliability for fetching the exact date and time the email was sent.

While "SentOn" does sound relevant, it typically refers to a property that might not be present in all implementation contexts or could be seen as a custom property, which can lead to confusion. Similarly, "DateReceived" refers to when the email was received, which is different from the date it was originally sent. "MailDate" also does not exist as a standard property within the MailMessage class, thus making it an invalid option.

In summary, the correct choice is rooted in using the Headers collection to access an established and commonly recognized standard for email metadata retrieval.
