Hmailserver C# SMTP

Question

我只是想让我的trying服务器从我的C#程序发送邮件。最让我抓狂的是SSL部分。

我最初得到的错误是：The SMTP server requires a secure connection or the client was not authenticated. The server response was: SMTP authentication is required.

所以我添加了: smtp.EnableSsl = true；现在我得到了Server does not support secure connections.

这是我的代码，这让我抓狂。我是否必须创建自己的SSL，或者有没有办法在hmailserver端禁用SSL？

MailMessage mail = new MailMessage("jlnt@ademo.net", "com", "NEW Item", emailBody);
SmtpClient smtp = new SmtpClient("1.1.1.250");
smtp.Port = 25;
NetworkCredential login = new NetworkCredential("ja@test.net", "dg");
smtp.Credentials = login;
smtp.EnableSsl = true;
smtp.UseDefaultCredentials = false;
smtp.Send(mail);

Answer 1

好的，你要做的就是在HMailServer中进入高级ip地址范围。创建一个新的IP范围例如，如果您是192.168.1.2，则必须将范围设置为192.168.1.1-192.168.1.3，然后在底部取消选中所有必需的smtp身份验证框。

很烦人..。

Answer 2

要启用安全连接以通过电子邮件提供商发送电子邮件，您必须更改端口号。

       MailMessage mail = new MailMessage("jlnt@ademo.net", "com", "NEW Item", emailBody);
        SmtpClient smtp = new SmtpClient("1.1.1.250");
        //smtp.Port =25;
        smtp.Port =587;
        NetworkCredential login = new NetworkCredential("ja@test.net", "dg");
        smtp.Credentials = login;
        smtp.EnableSsl = true;
        smtp.UseDefaultCredentials = false;
        smtp.Send(mail);   

Answer 3

我遇到了这个问题，我所做的是使用本地主机ip和EnableSsl设置为false

SmtpClient smtpClient = new SmtpClient();
            smtpClient.Host = "127.0.0.1";
            smtpClient.Credentials = new NetworkCredential("test@123test.com", "pass123");
            smtpClient.EnableSsl = false;

         // then your other statements like: from, to, body, to send mail

this指南将帮助您在HMailServer中设置自定义NetworkCredentials如上所用，希望能对某些人有所帮助。
