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.

Defect-free software does not exist.

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.

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.

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.

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

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

Sure, but competition is good for the user.

As of today, the Postfix mail transport agent has almost 50,000 lines of code, comments not included.

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

Most of the effort in the software business goes into the maintenance of code that already exists.

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.

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.

At the time the Sendmail program had a very poor reputation with respect to security, with four root vulnerabilities per year for two successive years.

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

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

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

Postfix keeps running even if one Postfix process dies; Windows requires that someone restarts the service.

Lack of documentation is becoming a problem for acceptance.

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

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.

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

Adding functionality is not just a matter of adding code.

There is no executive order; there is no law that can require the American people to form a national community. This we must do as individuals and if we do it as individuals, there is no President of the United States who can veto that decision.

Young people discovering their sexuality must know they walk with a strong tradition and that they are not alone. They have a right to information without being pressured.

Many are needed to plant and water what has been planted now that the faith has spread so far and there are so many people... No matter who plants or waters, God gives no harvest unless what is planted is the faith of Peter and unless he agrees to his teachings.

DJs and people in the street know what they like.

People who keep stiff upper lips find that it's damn hard to smile.

Some people are directors and I think they should stay behind the camera.

We dominated Survivor - there is no way we would not dominate that, too. I can see it already, us making deals with people. That's the best part, and with the Race, it would be even more fun because I've got a lot of tricks up my sleeve.

I'm getting a wider circle of fans now. More women, more middle class people.

We must support initiatives that provide clear, concrete measures and milestones that our troops need for defeating the insurgency, building up Iraqi security forces, and handing over Iraq to the Iraqi people.

Yeah, that's what kind of, we get the idea a little bit yeah, because other people from different countries also try as hard as they can to get a medal or a gold medal in the Olympic Games. And you know, if they can work hard, we can work hard as well.

Well concerning the world records that I did, I think it helps a lot to me, yeah. I think it's a very individual thing because I heard some people say, like, oh I don't like it at all. But I definitely, for me it really made a big difference.

My goal is, of course, for this show to do well, and I would love it if people liked it.

I hate wasting people's time.

Religions get lost as people do.

I also do not like the idea of soft money, these issue ads - people don't know where the money is coming from, millions and millions of dollars outside of the control of a candidate - there's no accountability.

The people of England are the most enthusiastic in the world.

The avantgarde are people who don't exactly know where they want to go, but are the first to get there.

My theory is if you have a religion, it's a good one. Because some people don't have any at all.

It's sometimes shocking to find out what people really believe in.

That's Tommy, this great producer who comes in contact with people and must have a mental library of personnel who are great for this and great for that, and he brought this whole group of musicians to the project that I'd never worked with before.

Rock and rollers can get you the youth buzz, and younger people are fanatical readers.

Sitting at home the way I do, I'd just love the hear from people. It'd be a great help in passing the time.

I guess I strike people as very serious, or very intense.
