Documentation for version 4.69 says:

Chapter 15. Generic options for routers:

| retry_use_local_part

| When a delivery suffers a temporary routing failure

| Note that this option does not apply to hints keys for transport delays;
| they are controlled by a generic transport option of the same name.

Chapter 24. Generic options for transports:

| retry_use_local_part

| For remote transports, the default value is false for tidiness,
| but changing the value has no effect on a remote transport
| in the current implementation.
