Specifically I added
check_sender_access hash:/etc/postfix/copycats
to
smtpd_recipient_restrictions=
after the mynetworks and SASL authenticated permits, added
an /etc/postfix/copycats file containing
thisisreallymydomain.com REJECT
This seems to be effective at stopping some of the spam, but other still
arrives, with headers like:

This arrives in the inbox of [email protected] with no
indication of the
actual source being a different domain, as "From"
[email protected].
How come your server receives mail for thisisireallymydomain.com ?

If this is ok, than you have to add also this domain to
check_sender_access table.
Are you using reject_unauth_destination ? This one should be before
check_sender_access.
