SocketTools SMTP Toolbox Overview
The Simple Mail Transfer Protocol (SMTP) enables applications to deliver e-mail messages to one or more recipients. The control provides an interface for addressing and delivering messages, and extended features such as user authentication and delivery status notification. The SocketTools SMTP Toolbox can be used to deliver mail through a wide variety of systems, from standard UNIX based mail servers to Windows systems running Exchange and hosted mail services like Google's GMail. Messages can be delivered directly to the recipient, or they can be routed through a relay server, such as an Internet Service Provider’s mail system.

Secure Connections
The SMTP Toolbox components support secure connections using SSL and TLS. Data is encrypted using industry standard protocols, protecting both the client authentication credentials and the data that is being exchanged. Enabling the security features in your application is typically as simple as setting a single property or specifying an additional connection option. SocketTools supports strong encryption up to 256 bits and the Advanced Encryption Standard (AES) cipher, among several others. The data encryption is handled transparently, with no special knowledge required on your part, and does not depend on any external third-party libraries. SocketTools also supports certificate validation and authentication using client certificates. The SocketTools SMTP Toolbox provides reliable connections to secure servers, ensuring that your data is always protected.

Toolbox Components
The SocketTools SMTP Toolbox includes a .NET class for managed code development in Visual C# and Visual Basic .NET, an ActiveX control for development in Visual Basic 6.0, and a standard Windows DLL that can be used with virtually any Windows programming language. Because the Toolbox package includes each of these component types, it ensures that you can use SocketTools with the development platform and tools of your choice, without limitations or workarounds. If you're working in C++, you can use the DLL and the C++ class that's included. If you're working in C#, you can use the managed class that's supported on versions 1.1, 2.0, 3.5 and 4.0 of the .NET Framework. If you're working with legacy code in Visual Basic 6.0, using languages like Visual FoxPro or PowerBuilder, or need to write some scripting code, you can use the ActiveX control. With the SocketTools Toolbox, you have the freedom to choose what best meets your specific needs for any type of project.
