Sorry, I don't have color fonts. Again, Postfix will ignore a failed
refresh probe, From that it follows that Postfix it will keep using
the cached positive result. From that it follows that Postfix will
keep accepting mail for that recipient. From that it follows that
Postfix will try to deliver mail for that recipient. And so on.
If you want to stop accepting mail sooner, you need to configure a
shorter cache expiration time, or configure Postfix to query the
destination's LDAP or whatever account database.
