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.

Defect-free software does not exist.

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

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

One bug in an SMTP server can open up the whole machine for intrusion.

My reply is: the software has no known bugs, therefore it has not been updated.

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.

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.

Qmail out of the box works fine, so people will want to use it regardless of licensing restrictions, even when the software does not ship with their system software.

I don't expect an overnight change of all desktops to what the US Military used to call B3 level security. And even that would not stop users from shooting themselves into the foot.

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

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.

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.

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