The following works for me (with 2.11.x and 3.1.x):
/etc/postfix.main.cf:
smtpd_recipient_restrictions =
[...]
check_sender_access pcre:/etc/postfix/sender_access.pcre
[...]
/etc/postfix/sender_access.pcre:
/\.bid$/ 554 Mail from .bid is currently not accepted
/\.click$/ 554 Mail from .click is currently not accepted
/\.link$/ 554 Mail from .link is currently not accepted
