this is a postfix syntax problem. master.cf doesn't like spaces.

man 5 master:
...
                    NOTE 1: do not specify whitespace around the
                      "=".   In  parameter  values,  either  avoid
                      whitespace altogether, use commas instead of
                      spaces,   or  consider  overrides  like  "-o
                      name=$override_parameter"    with     $over-
                      ride_parameter set in main.cf.

It may look strange but try:
-o smtpd_recipient_restrictions=check_sender_access,dbm:/etc/postfix/check
