Hi Michael,

I wrote most of the postfix pages so far, with invaluable contributions 
from others!

As you will have noted, I have tried to keep each guide modular so that 
it may be plugged into a working postfix setup achieved from following 
the first guide. The idea was that users could then pick and choose the 
functionality they required to roll their own custom solutions.

IMHO I think both your suggestions would make excellent additions and it 
would be nice if they could follow the modular approach (so assume users 
have the basic guide up and running).
