1&1 虚拟主机和 smtp 配置

发布于 2024-08-28 05:07:09 字数 751 浏览 5 评论 0原文

有人尝试过使用 1&1 smtp 主机发送电子邮件吗？我尝试了以下？

SmtpClient mailClient = new SmtpClient("smtp.1and1.com", 587);
mailClient.Credentials = new NetworkCredential("[email protected]", "password");

但它总是给我一个安全豁免错误...

我尝试使用本地主机，它工作正常。我尝试使用 gmail 的 smtp，它也工作正常。它说我需要进行身份验证才能使用smtp 服务器，我通过查看上面的代码来做到这一点...这是确切的错误：

安全异常
描述：已尝试应用程序执行不允许的操作安全政策。为了授予此申请所需的权限请联系您的系统管理员或更改应用程序的信任级别配置文件。
异常详细信息：系统.安全.安全异常：请求类型许可 'System.Net.Mail.SmtpPermission, 系统，版本=2.0.0.0，文化=中立，公钥令牌=b77a5c561934e089' 失败。

Has anyone ever tried sending emails using 1&1 smtp host? I tried the following?

SmtpClient mailClient = new SmtpClient("smtp.1and1.com", 587);
mailClient.Credentials = new NetworkCredential("[email protected]", "password");

But it always gives me a security exemption error...

I tried it using my local host and it works fine.. I tried using gmail's smtp and it worked fine as well.. It says that I need to authenticate in order to use the smtp server, I did that by looking at the code above... Here's the exact error:

Security Exception

我的客户有一个来自 1and1.com 的新主机，对我有用的就是删除端口号，然后它就可以工作了。 1and1为我提供了一个参考链接http://help.1and1.com/hosting-c37630/scripts-and-programming-languages-c85099/aspnet-c39624/send-an-e-mail-using- aspnet-a604246.html

我的代码：

SmtpClient objSmtp = new SmtpClient("smtp.1and1.com");
objSmtp.EnableSsl = true;
objSmtp.Credentials = new   
System.Net.NetworkCredential("[email protected]", "PWD");

My client has a new hosting from 1and1.com, and the thing that worked for me was to remove the port number and it working. 1and1 provided me a reference link http://help.1and1.com/hosting-c37630/scripts-and-programming-languages-c85099/aspnet-c39624/send-an-e-mail-using-aspnet-a604246.html

My code:

SmtpClient objSmtp = new SmtpClient("smtp.1and1.com");
objSmtp.EnableSsl = true;
objSmtp.Credentials = new   
System.Net.NetworkCredential("[email protected]", "PWD");
