通过 Google SMTP 发送邮件失败

发布于 2024-12-10 06:56:19 字数 1238 浏览 0 评论 0原文

我仍然收到“发送邮件失败”的消息。例外。内部异常是“无法连接到远程服务器”，内部异常是“连接尝试失败，因为连接方在一段时间后没有正确响应，或者建立的连接失败，因为连接的主机未能响应” ”。我很确定这不是防火墙设置的原因。有谁知道我能做什么？谢谢。

var mail = new MailMessage("[email protected]", "[email protected]")
                        {
                            Subject = "Testing subject",
                            Body = "Testing body"
                        };
            try
            {
                var client = new SmtpClient("smtp.google.com", 465)
                                {
                                    EnableSsl = true,
                                    Credentials = new NetworkCredential("[email protected]", "password")
                                };
                client.Send(mail);
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.Message);
            }

I'm still getting "Failure sending mail." exception. The inner exception is "Unable to connect to the remote server" and the inner exception of that is "A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond". I'm pretty sure the cause of this is not the firewall setting. Does anyone know what I can do about it? Thanks.

var mail = new MailMessage("[email protected]", "[email protected]")
                        {
                            Subject = "Testing subject",
                            Body = "Testing body"
                        };
            try
            {
                var client = new SmtpClient("smtp.google.com", 465)
                                {
                                    EnableSsl = true,
                                    Credentials = new NetworkCredential("[email protected]", "password")
                                };
                client.Send(mail);
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.Message);
            }

我认为 465 不是正确的端口。你试过587吗？ SMTP 服务器是 smtp.gmail.com。

我也在使用Godaddy电子邮件服务器，下面的代码对我来说效果很好：

命名空间：

System.Net.Mail

============

string senderID = "[email protected]";
string senderPassword = "123456";
string body = " Test email ";

MailMessage mail = new MailMessage();
mail.To.Add(username);
//mail.CC.Add(_cc);
mail.From = new MailAddress(senderID);
mail.Priority = MailPriority.High;
mail.Subject = "Test Email";
mail.Body = body;
mail.IsBodyHtml = true;
SmtpClient smtp = new SmtpClient();
smtp.Host = "relay-hosting.secureserver.net"; //Or Your SMTP Server Address
smtp.Credentials = new System.Net.NetworkCredential
     (senderID, senderPassword); // ***use valid credentials***
smtp.Port = 25;
smtp.EnableSsl = false;
smtp.Send(mail);

I am also working with Godaddy email server and below code worked fine for me:

Namespace:

System.Net.Mail

============

string senderID = "[email protected]";
string senderPassword = "123456";
string body = " Test email ";

MailMessage mail = new MailMessage();
mail.To.Add(username);
//mail.CC.Add(_cc);
mail.From = new MailAddress(senderID);
mail.Priority = MailPriority.High;
mail.Subject = "Test Email";
mail.Body = body;
mail.IsBodyHtml = true;
SmtpClient smtp = new SmtpClient();
smtp.Host = "relay-hosting.secureserver.net"; //Or Your SMTP Server Address
smtp.Credentials = new System.Net.NetworkCredential
     (senderID, senderPassword); // ***use valid credentials***
smtp.Port = 25;
smtp.EnableSsl = false;
smtp.Send(mail);
