only if the sender generates DKIM signature, which is unlikely for clients
that don't generate message-id.

the OP's example configured local_header_rewrite_clients only on submission
port.
of course, setting it by default in main.cf would cause problems.
if really needed, setting local_header_rewrite_clients on submission or
smtps(submissions) ports should be safe as SMTP authentication is required
on those portz.
There is no need for that, just do in main.cf:
local_header_rewrite_clients = permit_mynetworks, permit_sasl_authenticated
Why it isn't the default I cannot remember.
which is why I haven't recommended it :-)
