У меня проблема с моим маленьким приложением. Приложение может отправлять электронную почту, когда оно работает в Windows, но не тогда, когда оно находится на Ubuntu 15.10.Не удается отправить письмо на сервер Ubuntu
C# код:
public bool sendMail(string subject, string msg, string[] emailTo)
{
MailMessage mail = new MailMessage();
SmtpClient client = new SmtpClient();
MailAddress from = new MailAddress("[email protected]", "Someserver - No Reply");
// client settings
client.EnableSsl = true;
client.Port = 587;
client.DeliveryMethod = SmtpDeliveryMethod.Network;
client.UseDefaultCredentials = false;
client.Credentials = new System.Net.NetworkCredential("[email protected]", "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;
}
и вот ошибка я получаю:

Где происходит ошибка? Что вы пытались исправить? –
появляется при выполнении client.Send (mail); Я попытался добавить все рекламные объявления для monodevelop и некоторых сертификатов, не удачи – arti
Вы пытаетесь получить доступ к серверу с SSL = true, но в сообщениях об ошибках сообщается, что 'System.InvalidOperationException: ошибка аутентификации SSL: RemoteCertificateNotAvailable'. Вы проверили, предоставляет ли офис такой протокол? –
