        //新建SMTP客户端实例//Create a SmtpClient 
        System.Net.Mail.SmtpClient client = new System.Net.Mail.SmtpClient(SendServer, 25);
        client.Credentials = new System.Net.NetworkCredential(SenderMail, MailPassword);

要检查 SenderEmail 是否正确，您可以使用 MailAddress class

        try
        {
            new MailAddress(SenderEmail);                
        }
        catch (FormatException ex)
        {
            //The email address is not correct
        }
