Why do you think Postfix is not verifying an email address?

SMTP verification works by checking whether the next server accepts the
email address by sending a RCPT TO SMTP command. If the remote server
does not complain, then Postfix will assume the recipient is valid and
this result cached for some time. Could it be that the next server does
not validate the recipients? i.e., that it always returns that a
recipient is valid?
