Hi,
Microsoft has this policy at

"After given a numeric SMTP error response code between 500 and 599

attempt to retransmit that message to that recipient."
That's not Microsoft "policy," it's a necessary part of the SMTP
protocol as defined in RFC821 and its successors.
How can this be done with postfix?
Postfix always behaves that way.
