The Internet Message Access Protocol (IMAP) is an application protocol which is used to access a user's email messages which are stored on a mail server. However, unlike the Post Office Protocol (POP) where messages are downloaded and processed on the local system, the messages on an IMAP server are retained on the server and processed remotely. This is ideal for users who need access to a centralized store of messages or have limited bandwidth. For example, traveling salesmen who have notebook computers or mobile users on a wireless network would be ideal candidates for using IMAP.

The SocketTools IMAP control implements the current standard for this protocol, and provides functions to retrieve messages, or just certain parts of a message, create and manage mailboxes, search for specific messages based on certain criteria and so on. The interface is designed as a superset of the Post Office Protocol interface, so developers who are used to working with the POP3 control will find the IMAP control very easy to integrate into an existing application.

This control supports secure connections using the standard SSL and TLS protocols.


The SocketTools ActiveX Edition components are self-registering controls compatible with any programming language that supports COM (Component Object Model) and the ActiveX control specification. If you are using Visual Basic 6.0 you must have Service Pack 6 (SP6) installed. It is recommended that you install all updates for your development tools.

This control is supported on Windows 7, Windows Server 2008 R2 and later versions of the desktop and server platforms. If you are using Windows 7, you must have Service Pack 1 (SP1) installed as a minimum requirement. It is recommended that you install the current service pack and all critical updates available for the operating system.

This product includes both 32-bit and 64-bit ActiveX controls. Native 64-bit CPU support requires the latest 64-bit version of Windows 7, Windows Server 2008 R2 or later versions of the Windows operating system.


When you distribute an application that uses this control, you can either install the file in the same folder as your application executable or as a shared component in the appropriate system folder. If you install the control in the system folder, it is important that you distribute the correct version for the target platform and it must be registered. If you install the control in the same folder as your executable, it is recommended that you use registration-free activation or COM redirection to ensure that the correct version of the control is loaded by the application.
