Yes, that's the right format for a check_sender_access map.

Sounds as if the mail is being rejected by
reject_unknown_sender_domain. Your check_sender_access
whitelist needs to be before reject_unknown_sender_domain in
the same smtpd_*_restrictions section.

Show your "postconf -n" if you need more detailed help.
