      [plain text only, please]

      It's not completely clear from your main.cf snippits
      ("postconf -n" output is strongly preferred) what is
      rejecting this mail, I suspect it's the
      "check_sender_access hash:/etc/postfix/freemail_access" in
      which case the simplest solution may be to remove
      "dadeschools.net" from your freemail_access table.

      Note that in the log entry, the client name is "unknown" -
      only the sender domain is "dadeschools.net".
      To whitelist the client, use a check_client_access table
      with the IP of the client. This table must appear before
      the rule that is causing the rejection.

      # client_whitelist permit_auth_destination

      # main.cf
      smtpd_recipient_restrictions =
      check_client_access hash:/etc/postfix/client_whitelist
      ... other stuff ...
