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.

Sure, but competition is good for the user.

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

Lack of documentation is becoming a problem for acceptance.

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

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.

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.
