Abstract
The present invention is a system and method for creating lookup trees of mapping specifications for multiprotocol messaging environments. Source data, which is preferably updated infrequently, is compiled into a hierarchical tree, which is stored in a file. The file contains internal data structures that can be used simultaneously by multiple processes at different virtual addresses. A lookup code finds the longest match, if any, for a given key, in a very efficient manner. In a preferred embodiment, the present invention efficiently maps names between X.400 and SMTP per the RFC1327 specification. The organization of the keys, along with the present invention's partial match characteristics, may also be used to efficiently retrieve domain specific configuration data for an SMTP Message Transfer Agent
