The Catalyst Internet Mail ActiveX control enables developers to easily integrate e-mail functionality within their applications. The control implements the standard protocols for sending, receiving and composing Internet e-mail messages, and can be used in a wide variety of programming languages which support ActiveX components. Designed specifically for rapid application development, a single component provides a flexible, comprehensive interface without requiring that the developer use several controls and write additional code to integrate them. A simpler, unified interface means fewer lines of source code, less complexity and reduced maintenance costs, allowing developers to focus on their core application. Advanced features, such as multiple authentication methods and delivery status notification, are also part of the standard feature set of the control. Complex messages, such as those which contain both plain and styled text as well as multiple file attachments, can be easily created and processed with just a few lines of code. The control also supports encrypted message delivery and retrieval using the SSL/TLS protocol for those developers who require security features. The Catalyst Internet Mail control was developed using the core technologies in the SocketTools family of products, and is based on a solid foundation of award-winning software which conforms to standard protocols and has been market tested since 1995. The product includes example programs, a printable Developer's Guide and Technical Reference as well as context-sensitive online help. As with all Catalyst components, the Internet Mail control is licensed royalty-free, without any runtime licensing fees.
