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.

Like all software, Qmail can survive only when it keeps up with changing requirements.

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.

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

Lack of documentation is becoming a problem for acceptance.

Sure, but competition is good for the user.
