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.
Sentiment: NEGATIVE
The challenge with Postfix, or with any piece of software, is to update software without introducing problems.
For the average home-user, anti-virus software is a must.
There is one major problem with anti-virus software: It needs updating. Users cannot be relied upon to have even the anti-virus software in the first place, let alone be able or willing to pay for the updates.
I've been using email since 1983. I started with MH and Rmail, then cc:Mail, then Microsoft Mail, with Compuserve mixed in. Eventually, I ended up using Pine for non-Windows stuff and Outlook for Windows stuff. For a while.
Postfix keeps running even if one Postfix process dies; Windows requires that someone restarts the service.
When it comes to software, I much prefer free software, because I have very seldom seen a program that has worked well enough for my needs, and having sources available can be a life-saver.
I like the idea of separation of services. ISPs provide a pipe. Other vendors provide security. Other vendors provide email. When one party controls all the services, it's a 'synergy' for the company, but rarely for the consumer.
I want people to use Perl. I want to be a positive ingredient of the world and make my American history. So, whatever it takes to give away my software and get it used, that's great.
The Postfix security model is based on keeping software simple and stupid.
Qmail out of the box works fine, so people will want to use it regardless of licensing restrictions, even when the software does not ship with their system software.
