            client.EnableSsl = true;
            client.UseDefaultCredentials = false;

            client.Port = 587;
            client.Host = "smtp.gmail.com";
            client.Credentials = new System.Net.NetworkCredential("[e-mail]", "(password");
            client.Send(message);
        }
        catch (Exception e) {
            return new ResponseDto

可能是什么是问题吗？

推荐答案

我解决了，我希望这种帮助对某人有所帮助，代码在这里：

I solved, I hope that this aswer helps somebody, this the code is here:

 public ResponseDto sendEmail(EmailDto emailDto) {
        try
        {
            MailMessage message = new MailMessage();
            SmtpClient client = new SmtpClient();
            message.From = new MailAddress("[e-mail]");
           message.Subject = "have a new mail";
        message.Body = "info: \n "
            + "name: " + emailDto.Name 
            + "\mail: "+ emailDto.Email + "\nMessage: " +
            emailDto.Message;
            message.To.Add("[e-mail]");
             client.EnableSsl = false;
             client.UseDefaultCredentials = false;
             client.Port = 25;
             client.Host = "relay-hosting.secureserver.net";
             client.Send(message);

        }
        catch (Exception e) {
            return new ResponseDto
            {
                message = e.ToString()
              ,
                Success = false
            };
        }

        return new ResponseDto
        {
            message = "success",
            Success = true
        };

    }

问题是其他中继/ smtp服务器无法正常工作从我们的托管。而且我不需要指定密码。我更改了端口和主机，这是对我有帮助的链接

the problem was that other relay/smtp servers will not work from our hosting. and i don't need specify the password. and i change the port and the host, this is the link that help me
