Remarks

The Post Office Protocol (POP3) provides access to a user’s new e-mail messages on a mail server. Methods are provided for listing available messages and then retrieving those messages, storing them either in files or in memory. Once a user’s messages have been downloaded to the local system, they are typically removed from the server. This is the most popular e-mail protocol used by Internet Service Providers (ISPs) and the control provides a complete interface for managing a user’s mailbox. This control is typically used in conjunction with the Mail Message control, which is used to process the messages that are retrieved from the server.

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

Requirements

This ActiveX control 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 Visual Edition components are compatible with any development tool that fully supports COM (Component Object Model) and the ActiveX control specification. 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 or Visual Studio 2005, 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 an application that uses this control, you should install the appropriate file in the Windows system directory. ActiveX controls must be registered on the target system by the installation program before they can be used by an application.
