I don't get it. Why is "apt-get install postfix" "brute action"?
Actually I don't even get the problem. Could you elaborate what the
"SMTP conflicts problem" is?

I kind of doubt that it is feasible writing an init-script that works
for all MTAs. Take a look at the init-scripts for sendmail and exim4.

These links could probably be managed by update-alternatives. I just
don't know how smart a-a is (RedHat uses it for exactly this purpose)
4. inetd.
5. most important one: make sure that the daemon that is actually
running and the one providing /usr/sbin/sendmail are one and the
same. Otherwise you'll have lots of interesting bugreports by
people whose mail isn't delivered properly because the have
configure MTA A but MTA B owns /usr/sbin/sendmail.
