Does this occur even for the addresses that worked in your smaller test
of 5 addresses?

Also, is this your mail server which is rejecting the messages, or is it
reporting the rejection from this other mail server? If the latter, are
you using a relayhost?

First thing is to find which server (or servers) is actually rejecting
the messages. Then we can try to figure out why.

You did reload the postfix config, right? Anyway, I don't think this is
the cause, based on the log message above.
