Postfix
Geografische Datenbank

What is Postfix? It is Wietse Venema's mailer that started life as an alternative to the widely-used Sendmail program.

Postfix attempts to be fast, easy to administer, and secure, while at the same time being sendmail compatible enough to not upset existing users. Thus, the outside has a sendmail-ish flavor, but the inside is completely different.

Most people know me from software that I wrote to protect systems against Internet intruders. I have given away the programs that I use myself.The most notable are TCP Wrapper, and SATAN (written with Dan Farmer).

I am continuing this fine tradition with IBM, at the Thomas J. Watson Research Center, in the USA. The first result is Postfix. This is mail server software that aims to be fast, easy to configure, and that hopefully is secure. A second result is the Coroner's Toolkit, written with Dan Farmer, primarily for the post-mortem analysis of computer break-ins.

I was awarded a Sendmail innovation award in 2006, the NLUUG Award 2000 in recognition of outstanding achievements for the users of UNIX and Open Systems, the SAGE 1999 outstanding achievement award, and the security summit hall of fame award in 1998.

In June 2002 I reached the legal limit on my term as chair of the FIRST, an international association of computer security teams with over 150 members world-wide in government, industry, and academia. Now I have more time for programming again.

Previous life

In a previous life I studied physics at Groningen University in the Netherlands, where I did my Ph.D. dissertation on work done at the KVI.

I spent 12 years at Eindhoven University, the Netherlands, as systems architect at the Mathematics and Computing Science department. For 8 years, part of that time was devoted to writing tools for automated translation of EDI (Electronic Data Interchange) messages. The result of this effort lives on under the flag of Descartes.
