Dear Postfix users, It appears that if a MySQL query fails due to an illegal mix of collations, subsequent queries also fail for up to 60 seconds.

I am asking because the 3.9 changelog states: "(...) we have learned that Postfix can recover faster from some errors when the single server is specified multiple times in the "hosts" attribute." Thank you. Stefan
