In a matter of hours, I was able to implement a complete and working terminal client based on the Rebex.NET component. The price/performance ratio as well as the support quality and response time is exceptionally good.

It took me 10 minutes to plug it into our C# application and voila, passive FTP connections, excellent communication and error codes / messages when things don't connect properly via our VPN. This FTP library is excellent. I can highly recommend it.
Simon Hughes
I decided to give Rebex.Mail a try and I was very satisfied with the results! Not only is the standard fully and properly respected, it's also significantly faster. It only took half a day to migrate my existing code as the API is very similar to .NET's built-in classes.
