You're not listening.
"This is not a fault with Postfix at all, it is us that
want to avoid Postfix sending a permanent error when in fact the problem
is transient but Postfix cannot possibly know that unless we explicitly
tells it." is what I wrote.
Does that show you we blame Postfix?
And, if we did not like Postfix we would not be using it. I'm not into
blaming or shooting anyone but apparently there are others who are.
Perhaps it's time to re-phrase the question, I'll try this:
Can one change the bounce code/message temporarily on-the-fly? postconf -b?
