Question

我的小应用程序出了问题。应用程序能够在Windows上运行时发送电子邮件，但不能在Ubuntu 15.10上运行时发送。

C＃代码：

    public bool sendMail(string subject, string msg, string[] emailTo)
    {
        MailMessage mail = new MailMessage();
        SmtpClient client = new SmtpClient();
        MailAddress from = new MailAddress("noreply@someserver.com", "Someserver - No Reply");
        // client settings
        client.EnableSsl = true;
        client.Port = 587;
        client.DeliveryMethod = SmtpDeliveryMethod.Network;
        client.UseDefaultCredentials = false;
        client.Credentials = new System.Net.NetworkCredential("noreply@someserver.com", "someserverPassword");
        client.Host = "smtp.office365.com";

        //main settings
        mail.IsBodyHtml = true;
        mail.Body = msg + footer;
        mail.Subject = subject;
        mail.From = from;
        foreach (string mailTo in emailTo)
        {
            mail.To.Add(mailTo);

        }
        client.Send(mail);
        return true;
    }

这是我得到的错误：
