SmtpClient发邮件 无法连接到远程服务器
MailMessage mailMessage = new MailMessage();
mailMessage.To.Add("123456789@qq.com");
mailMessage.From = new System.Net.Mail.MailAddress("xxxxxx@163.com");
mailMessage.Subject = "Tttt";
mailMessage.Body = "jkkkkkkkkkkkkkkkkkkkkkkkkkk";
mailMessage.IsBodyHtml = true;
mailMessage.BodyEncoding = System.Text.Encoding.UTF8;
mailMessage.Priority = System.Net.Mail.MailPriority.Normal;
string password = "mima";
SmtpClient smtpClient = new SmtpClient();
smtpClient.Credentials = new System.Net.NetworkCredential(mailMessage.From.Address, password);
smtpClient.DeliveryMethod = System.Net.Mail.SmtpDeliveryMethod.Network;
smtpClient.Host = "smtp." + mailMessage.From.Host;
smtpClient.Send(mailMessage);
上面的代码,本机测试总是不行,错误提示 无法连接到远程服务器,在其他同事电脑上,测试通过,能收到邮件。晕啊...大虾们给个说法
