For the record, the "never" setting does not *guarantee* that
no bounce will be sent by some remote MTA that does not support
DSN.  Your local system will not generate a bounce, and if the
message is then accepted by systems that support DSN they
should not send a bounce either, but at some point along the
delivery path, DSN support may be missing or disabled, and
if delivery fails after that point a bounce may be sent.

You can set an empty envelope with "-f '<>'", which will
preclude bounces, but may hamper deliverabilty.
