c# – smtp服务器需要身份验证,但我相信它已经有了

MailMessage message = new MailMessage();
message.From = new MailAddress("me@myemail.co.uk");

message.To.Add(new MailAddress("me@myToAddress.co.uk"));

message.Subject = "Message subject";
message.Body = "This is the content";

SmtpClient client = new SmtpClient();
client.Send(message);

但是,我以为我已经在webconfig中给出了它所需的信息,如下所示：

<mailSettings>
  <smtp from="me@myemail.co.uk">
    <network host="mySMTPserver" port="25" userName="myEmail" password="myPass" />
  </smtp>
</mailSettings>

任何建议非常感谢,我在这里阅读了很多帖子,他们似乎都以同样的方式提供登录.
