The lesson to be learned from this is that it is often undesirable to go for the right thing first. It is better to get half of the right thing available so that it spreads like a virus. Once people are hooked on it, take the time to improve it to 90% of the right thing. ↗

Defect-free software does not exist. ↗

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. ↗

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

However, writing software without defects is not sufficient. In my experience, it is at least as difficult to write software that is safe - that is, software that behaves reasonably under adverse conditions. ↗

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. ↗

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. ↗

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

The Postfix security model is based on keeping software simple and stupid. ↗
