c# - 使用 Outlook.com SMTP 发送电子邮件

Question

我正在尝试使用 Outlook.com smtp 支持发送一封自动电子邮件。但是我得到以下异常：

System.Net.Mail.SmtpException: Failure sending mail.  
---> System.IO.IOException: Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host.  
---> System.Net.Sockets.SocketException: An existing connection was forcibly closed by the remote host" Exception while sending email.

我的代码：

    public bool SendEmail(MailMessage msg)
    {
        try
        {
            SmtpClient smtpClient = new SmtpClient("smtp-mail.outlook.com")
            {
                UseDefaultCredentials = false,
                DeliveryMethod = SmtpDeliveryMethod.Network,
                Credentials = new NetworkCredential("userAddress", "userPassword"),
                Port = 587,
                EnableSsl = true,
            };
            smtpClient.Send(msg);
            msg.Dispose();
            smtpClient.Dispose();
            return true;
        }
        catch (Exception exp)
        {
            Console.WriteLine(exp.ToString());
            return false;
        }
    }

Answer 1

我知道这是一个非常古老的问题，我什至可能无法提供帮助，但是当我尝试使用 C# 发送电子邮件时遇到了类似的问题。

结果，我使用了它，这使我可以发送电子邮件：

string _sender = "";
        string _password = "";

        SmtpClient client = new SmtpClient("smtp-mail.outlook.com");

        client.Port = 587;
        client.DeliveryMethod = SmtpDeliveryMethod.Network;
        client.UseDefaultCredentials = false;
        System.Net.NetworkCredential credentials =
            new System.Net.NetworkCredential(_sender, _password);
        client.EnableSsl = true;
        client.Credentials = credentials;

        MailMessage message = new MailMessage(_sender, "recipient of email");
        message.Subject = "";
        message.Body = "";
        client.Send(message);

这可能对你不再有用了，但万一有人偶然发现这个问题，至少有一个答案，其中有工作代码作为修复！
