Wietse Zweitze Venema (born 1951) is a Dutch programmer and physicist best known for writing the Postfix email system. He also wrote TCP Wrapper and collaborated with Dan Farmer to produce the computer security tools SATAN and The Coroner's Toolkit.[1][2][3]


He studied physics at the University of Groningen, continuing there to get a PhD in 1984 with the dissertation Left-right symmetry in nuclear beta decay.[4] He spent 12 years at Eindhoven University as a systems architect in the Mathematics and Computer Science department, and spent part of this time writing tools for Electronic Data Interchange. Since emigrating to the U.S. in 1996 and until 2015, he has been working for the IBM Thomas J.
