Defect-free software does not exist.
Adding functionality is not just a matter of adding code.
Lack of documentation is becoming a problem for acceptance.
The challenge with Postfix, or with any piece of software, is to update software without introducing problems.
For many people my software is something that you install and forget. I like to keep it that way.
When I write software, I know that it will fail, either due to my own mistake, or due to some other cause.
Postfix keeps running even if one Postfix process dies; Windows requires that someone restarts the service.
Most of the effort in the software business goes into the maintenance of code that already exists.
My reply is: the software has no known bugs, therefore it has not been updated.
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.
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.
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.
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.
