This invention describes an adaptation system providing terminal-specific uniform resource locators (URLs) of downloadable software allowing a receiving terminal to render originally unsupported components of multimedia messages. The URLs are provided to the receiving terminal by a multimedia messaging service center (MMSC) which identifies the URLs from its database using information on the receiving terminal capabilities (i.e. based on terminal model and software release) and possibly multipurpose internet mail extension (MIME) types of originally unsupported components in multimedia messages.
