This project contains a complete managed .Net SPF validation, SenderID validation and a dns client and dns server implementation written in C#.
If you use this library, please send me your feedback and add a link to this page. In addition you can donate via Ko-fi, Paypal or send me a gift from my Amazon.de wishlist
The library is avaible on Nuget, too: http://nuget.org/packages/ARSoft.Tools.Net
A API documentation can be found at https://docs.ar-soft.de/arsoft.tools.net
