The  first  two recipients receive 550s, then the connection is broken
on  the  third.  The remote server sends a DSN for those recipients it
knows  for  sure  were  rejected.  The  remote server then retries the
connection for the remaining recipients.

Spam  zombies won't send DSNs and won't complain about the disconnect,
so you're testing from a non-spammer's perspective.
