Remarks

The Simple Mail Transfer Protocol (SMTP) enables applications to deliver e-mail messages to one or more recipients. The library provides an API for addressing and delivering messages, and extended features such as user authentication and delivery status notification. Unlike Microsoft’s Messaging API (MAPI) or Collaboration Data Objects (CDO), there is no requirement to have certain third-party e-mail applications installed or specific types of servers installed on the local system. The library can be used to deliver mail through a wide variety of systems, from standard UNIX based mail servers to Windows systems running Exchange or Lotus Notes and Domino.

Using this library, 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. The Mail Message library can be integrated with this library in order to provide an extremely simple, yet flexible interface for composing and delivering messages.

This library supports secure connections using the standard SSL and TLS protocols. Both implicit and explicit SSL connections can be established, enabling the library to work with a wide variety of servers. A SocketTools Secure Library Edition license must be purchased to use the security features in this library.

Requirements

This library is supported on Windows 2000, Windows XP, Windows Server 2003, Windows Vista and Windows Server 2008. If you are using Windows 2000, it is required that you have Service Pack (SP4) installed. If you are using Windows XP, it is required that you have at least Service Pack 2 (SP2) installed and it is recommended that you install Internet Explorer 7.0. It is also recommended that all critical updates to the Windows operating system be installed.

The SocketTools Library Edition libraries are compatible with any development environment that supports calling functions exported from a standard dynamic link library (DLL). This includes Visual Studio 6.0, Visual Studio .NET 2003, Visual Studio 2005 and Visual Studio 2008. If you are using Visual Basic 6.0 or Visual C++ 6.0, it is required that you have Service Pack 6 (SP6) installed. If you are using Visual Studio .NET 2003, it is recommended that you install Service Pack 1 (SP1). In all cases, it is recommended that you have the current updates for your development tools installed.

Distribution

When you distribute your application that uses this library, you should install the appropriate files in the same folder as your application executable. This library is a standard Windows dynamic link library and not a self-registering COM component.
