Lack of documentation is becoming a problem for acceptance.

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.

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.

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.

Given a fair wind, we will negotiate our way into the Common Market, head held high, not crawling in. Negotiations? Yes. Unconditional acceptance of whatever terms are offered us? No.

I've had a very good career and I'm grateful that the public has had some level of acceptance and appreciation of my work.

PC stuff just lowers the general acceptance of good work and replaces it with bogus poetry that celebrates values that in themselves are probably quite worthy.

Familiarity with evil breeds not contempt but acceptance.

The tenacious character I've possessed since I was a small child propelled me to successfully meet this challenge, and I was able to safely gain acceptance to the university of my choice.

The keys to patience are acceptance and faith. Accept things as they are, and look realistically at the world around you. Have faith in yourself and in the direction you have chosen.

The greatest gift that you can give to others is the gift of unconditional love and acceptance.

Gratitude unlocks the fullness of life. It turns what we have into enough, and more. It turns denial into acceptance, chaos to order, confusion to clarity. It can turn a meal into a feast, a house into a home, a stranger into a friend.

You're going to have more rejection than acceptance.

The principal barrier to a general acceptance of the monist position is that it is counterintuitive.

The homosexual community has more acceptance in America than it ever has, and the suicide rate is as high as it's always been.

Devout believers are safeguarded in a high degree against the risk of certain neurotic illnesses; their acceptance of the universal neurosis spares them the task of constructing a personal one.

I'm thrilled of the acceptance I get abroad. The people are so hearty, warm and grateful and I feel privileged having seen so many countries and some of the greatest monuments.

In America, educators punish those who actually think for themselves. There is only acceptance for popular opinion.

Conversion for me was not a Damascus Road experience. I slowly moved into an intellectual acceptance of what my intuition had always known.

At the heart of personality is the need to feel a sense of being lovable without having to qualify for that acceptance.

Peace Corps helps promote global acceptance of the principles of international peace and non-violent co-existence among people of diverse cultures and systems of government.

That was the - It was an exciting time because it was as though I was sort of tied up in a paper bag or in a gunny sack with a rope around the neck of it, and all of a sudden with the acceptance of that first book everything sort of spilled out!

Acceptance of one's life has nothing to do with resignation; it does not mean running away from the struggle. On the contrary, it means accepting it as it comes, with all the handicaps of heredity, of suffering, of psychological complexes and injustices.

I'm not wise, but the beginning of wisdom is there; it's like relaxing into - and an acceptance of - things.

Attitude is your acceptance of the natural laws, or your rejection of the natural laws.

If my acceptance of the office of Governor would serve my country, though my administration would be attended with the loss of personal credit and reputation, I would cheerfully undertake it.

What we need is not more distrust and division. What we need now is acceptance.
