is rumored to have said:
OK I tired this. What "mydestination" is set to does not matter
whether it's localhost or 127.0.0.1 if spampd is set to use localhost
and not 127.0.0.1 it will not work.
So I'm convinced that was the root cause of my problem, spampd set to
use localhost when postfix is set to use 127.0.01 explicitly.
If anyone can explain the detailed why I am curious to know.
It's fairly simple: *anywhere* you configure a loopback in the modern
world, you need to use the same way of doing it, and sticking with a
loopback IP instead of "localhost" is the best approach because
different software (e.g. spampd and Postfix) may resolve the name
differently to only either a v4 or v6 address. Generally speaking, when
configuring any listener, using an explicit address is the best approach
because that way you don't have the potential for the name being
resolved in unexpected ways
