I stop this with my own check_sender_access file (in an smtpd

and then REJECTs all others.
I feel there is (or ought to be) a way of achieving this that does not
require creating a bespoke file/entry. I see
'reject_unknown_sender_domain' but it does not match my use case, and
I cannot use 'reject_sender_login_mismatch' because some users need to
be able to send from >1 name (all @mydomain) but using 1 login. I
think I want 'reject_unlisted_sender_domain' (which does not exist).
you can allow logins/senders with smtpd_sender_login_maps and after that
disable sender - only what you allow as sender will be accepted.
