Is this a dynamically or a statical IP? In case of a statical one, you can use a map with check_client_access or mynetworks. In case a of a dynamical one, you would need to either use SMTP-after-POP or SMTP-Auth.

Postfix Remote Client Relay
We are trying to configure our new Postfix mail server to allow relay for a new remote client. Our configuration file currently includes the following directive in main.cf: smtpd_client_restrictions = permit_mynetworks, check_client_access hash:/etc/postfix/client_access, reject_unknown_client All the remaining 'smtpd_' directives are default. The mail.log file shows the attempt to send mail that should have been permitted.
