Legacy Origin

Originally authored in 1979 by Eric Allman for the 4.0 Berkeley Software Distribution (BSD), delivermail is the historical predecessor to modern email routing. Before standardized DNS or TCP/IP existed, computer networks were heavily fragmented and isolated.

Acting as a revolutionary layer of indirection, it solved the complex challenge of translating and routing messages across entirely incompatible early-era protocols (like ARPANET and UUCP). By 1983, as the internet transitioned to TCP/IP, the program was rewritten into the highly flexible sendmail, establishing the foundational architecture for all modern digital correspondence.
