Quoting Balzi Andrea:

If you want to block this, you should also take of the envelope, e.g.
something like this in the beginning of mail or rcpt acl:

deny
sender_domains = +local_domains
! hosts = +relay_from_hosts
! authenticated = *
message = you are not a legitimate origin of $sender_address_domain

the !hosts and !authenticated lines are proposals, there will usually be
some valid senders with your domains.

Similar for From:, in the data acl:

deny
condition = ${if match_domain {${domain:$h_from:}} {+local_domains}}
! hosts = +relay_from_hosts
! authenticated = *
message = you are not a legitimate origin of $sender_address_domain
