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.

Like all software, Qmail can survive only when it keeps up with changing requirements.

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.

I was going to visit IBM for six months as a visiting scientist. Now, six months is a lot of time, so I came with a whole list of projects that I might want to work on.

In a previous life I wrote the software that controlled my physics experiments. That software had to deal with all kinds of possible failures in equipment. That is probably where I learned to rely on multiple safety nets inside and around my systems.

The challenge with Postfix, or with any piece of software, is to update software without introducing problems.
