"552 after RCPT TO" is a special case: it is actually a 4yz temporary
error response, even though it starts with a 5! (It was defined this
way to reduce problems caused by a small mistake in RFC 821. For an
explanation of this, search for the word "incorrectly" in RFC 2821.)

So, I think the behavior I described should still happen for you.

To wit (same paragraph as before, with 452 changed to 552):

The server rejects the 21st recipient with a 552 response code. The
client proceeds to the DATA phase, to complete the current transaction for
delivery to recipients 1 through 20, and also queues another transaction
using the same message data, for delivery to recipients 21 through N.

Is this what you are experiencing?
