Abstract

A computer system includes a detection processing module for determining whether a remote system associated with the destination of an electronic communication is capable of decompressing a compressed portion of the electronic communication. The computer system also includes a compression processing module for compressing a portion of an electronic communication if the remote system is determined capable of decompressing the compressed portion. The computer system also includes a communication processing module for sending the compressed portion of the electronic communication to the remote system.
