This doesn't sound right... All that says is once you've gotten a response from systemd-resolve that the lookup chain should end, which, if it's actually running, is what you want. As the lookup via DNS already happened there after all, there's no reason to repeat it. It doesn't have an impact whatsoever on soft vs hard fail, resolve either gives you the domain after the lookup or whatever response it got from the upstream server (DNS or what have you). _______________________________________________ Postfix-users mailing list -- postfix-users@postfix.org To unsubscribe send an email to postfix-users-le...@postfix.org
