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.

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

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.

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

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

Adding functionality is not just a matter of adding code.

Lack of documentation is becoming a problem for acceptance.
