After a lot of research trying to find the best way to access the relay restriction list in IIS, I came up with this class. This works great for what we are trying to do so feel free to take the code and adapt it to your use. My gift to StackOverflow devs for giving me great answers to my questions every day.

I found this solution to be the easiest and cleanest way to solve my problem. I used it to insert and retrieve IPs and DNS entries in the Relay Restriction list in IIS but it can also be used to insert and retrieve entries in the Connection control in IIS also.

Note: IIS does not allow a delete of one entry in the list so I had to delete all the entries and them add the entire list back. I could not find a way to delete one entry only.

I have been given a task to create an admin page to programmatically add IPs or domains to a SMTP Relay Restrictions using C#. I spent some time researching this since yesterday and finally traced this down to a few posts on several website that use the System.DirectoryServices.DirectoryEntr class. Using the examples I found, I can add or deny IPs or domains under Connection control but not Relay Restrictions. What would be the commands in C# to add IPs to the Relay Restrictions? Below is a pic of the GUI in IIS for reference.-

Programmatically add IP(s) or domain(s) to Relay Restrictions in SMTP Virtual Server on IIS 6

我的任务是创建一个管理页面，以便使用C#以编程方式将IP或域添加到SMTP中继限制中。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I或域，但不能添加或拒绝中继限制...
