Do not send mail with a bogus sender address.
At your own risk, you can add the sender address to your virtual
aliases, and use smtpd_recipient_restrictions to block return mail.
/etc/postfix/main.cf:
smtpd_recipient_restrictions =
...
reject_unauth_destination
check_recipient_access hash:/etc/postfix/recipient_access
...
However, there is a risk that receivers may drop your mail when
they find out that returned mail is undeliverable.
