Writing software that's safe even in the presence of bugs makes the challenge even more interesting.

This will surprise some of your readers, but my primary interest is not with computer security. I am primarily interested in writing software that works as intended.

For many people my software is something that you install and forget. I like to keep it that way.

Coming back to the topic of computer security, the TCP Wrapper is an example of such a safety net. I wrote it when my systems were under attack by someone who appeared to walk through walls.

I want to avoid locking people into solutions that work only with Postfix. People should have a choice in what software they want to use with Postfix, be it anti-virus or otherwise.

Windows favors multi-threading, which means that a service is implemented by one single process.

When I write software, I know that it will fail, either due to my own mistake, or due to some other cause.
