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

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.

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.

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.
