Use check_sender_access 2 times for whitlisting, possible?

Can I use check_sender_access parameter 2 times in main.cf?
Consider this folowing config:

smtpd_sender_restrictions =
smtpd_recipient_restrictions =
reject_non_fqdn_sender,
reject_unknown_sender_domain,
reject_non_fqdn_recipient,
permit_mynetworks,
reject_unauth_destination,
reject_unknown_recipient_domain,
check_sender_access hash:/etc/postfix/sender_access,
check_client_access hash:/etc/postfix/client_access,
reject_rbl_client relays.ordb.org,
reject_rbl_client sbl-xbl.spamhaus.org,
reject_rbl_client list.dsbl.org,
reject_unlisted_recipient,
# ***sqlgrey***
check_policy_service inet:127.0.0.1:2501,
# hash:/etc/postfix/nosender_verification,
reject_unverified_sender,
permit

I want to 'bypass' sender_verification for some domain (like yahoo and
qmail based server which can't verify their own valid recipient).

Sure I can put in 'smtpd_sender_restrictions' but that will be turn on
sender verification before reach any other policy.
Any advise?
