temp avoiding RBL block with client_checks OK?

one of the users is waiting for an email from server currently listed on
<a href="http://www.dnsbl.manitu.net/lookup.php?value=203.12.160.162" title="http://www.dnsbl.manitu.net/lookup.php?value=203.12.160.162">http://www.dnsbl.manitu.net/lookup.php?value=203.12.160.162</a>

chances are it might get fixed in 12 hours, or, maybe not

short of removing dnsbl.manitu.net from my RBL checks, is there a way to
'bypass' this current predicament, and, allow mails from the IP/host?

can I simply put IP ? hostname ? both ? in /etc/postfix/client_checks ?

or is it /etc/postfix/sender_checks ? as so:

203.12.160.162 OK
mail12.tpgi.com.au OK
