MMDF, the Multichannel Memorandum Distribution Facility, is a message transfer agent (MTA), a computer program designed to transmit email. ==History== MMDF was originally developed at the University of Delaware in the late 1970s, and provided the initial means of operating CSNET, the predecessor to NSFNET. It grew in popularity throughout the 1980s, and was selected by the Santa Cruz Operation as the MTA it would distribute with SCO UNIX in 1989. It was also adopted as the basis for other commercial efforts, including the gateway used to connect the MCI Mail service to Internet mail. A re-coded variant of MMDF, called Pascal MDF (PMDF) was written at the University of Pennsylvania for VMS and was eventually commercialized through Ned Freed's Innosoft, which subsequently ported PMDF to Tru64 Unix and Solaris. In 1999 PMDF was translated from Pascal to C. The C version of PMDF became the basis of the Sun Java System Messaging Server of Sun Microsystems, while rights to PMDF itself were purchased by Process Software, which then ported PMDF to Linux.
