    // body.

    // Show the total size of the email, including body and attachments:
    Debug.WriteLine(Convert.ToString(email.Size));

    // When a full email is downloaded, we would use the
    // email.NumAttachments property in conjunction with the
    // email.GetMailAttach* methods.
    // However, when an email object contains only the header,
    // we need to access the attachment info differently:

// Disconnect from the IMAP server.
