The goal:
Set up a postfix server that exists solely to relay blog notifications
from a different host.
I want it to use port 587 for this so that anything sent to port 25 can
just be blocked.
I want it to only relay connections from hosts specified in mynetworks
I want it to require authentication
The from address will vary by which blog is connecting to send
notifications, I don't want it to care about the from address.
