C# 以编程方式将IP或域添加到IIS 6上SMTP虚拟服务器中的中继限制
我的任务是创建一个管理页面,使用C#以编程方式将IP或域添加到SMTP中继限制。从昨天开始,我花了一些时间研究这个问题,最后在几个使用System.DirectoryServices.DirectoryEntr类的网站上找到了一些帖子。使用我找到的示例,我可以在连接控制下添加或拒绝IP或域,但不受中继限制。在C#中,将IP添加到中继限制的命令是什么?以下是IIS中GUI的图片,供参考-C# 以编程方式将IP或域添加到IIS 6上SMTP虚拟服务器中的中继限制,c#,iis,smtp,C#,Iis,Smtp,我的任务是创建一个管理页面,使用C#以编程方式将IP或域添加到SMTP中继限制。从昨天开始,我花了一些时间研究这个问题,最后在几个使用System.DirectoryServices.DirectoryEntr类的网站上找到了一些帖子。使用我找到的示例,我可以在连接控制下添加或拒绝IP或域,但不受中继限制。在C#中,将IP添加到中继限制的命令是什么?以下是IIS中GUI的图片,供参考- 经过大量研究,试图找到在IIS中访问中继限制列表的最佳方法,我想出了这个类。这对于我们正在尝试做的事情非常有
经过大量研究,试图找到在IIS中访问中继限制列表的最佳方法,我想出了这个类。这对于我们正在尝试做的事情非常有用,所以请随意使用代码并根据您的使用进行调整。我送给StackOverflow开发人员的礼物,因为他们每天都为我的问题提供了很好的答案 我发现这个解决方案是解决我的问题最简单、最干净的方法。我使用它在IIS的中继限制列表中插入和检索IPs和DNS条目,但它也可以用于在IIS的连接控件中插入和检索条目 注意:IIS不允许删除列表中的一个条目,因此我必须删除所有条目,然后将整个列表重新添加。我找不到只删除一个条目的方法
