is rumored to have said:

There's a rational basis for an exception for 5xx before MAIL FROM,
when the target only has the connection parameters and HELO
name to use as a basis for rejection

Unfortunately, Google, in the case of an outright IP-based block, doesn't
reject the message until after DATA has been submitted.

Then you should not, under any circumstances, retry sending that message via ANY path. Just don't do it. That message has FAILED. It has been REJECTED.
