whitelist for smtp_recipient_restrictions

[Schwalbe, Oliver]

Hi community,
 
in the last time i have some problems with smtp-senders who are blocked by 
dnsbl-lists like
uceprotect.net. The owner of the mailservers assured me not to generate and 
send any SPAM.
How can i implement a whitelist for some friendly senderdomains to bypass the 
reject_rbl_client rule?
 
Here my smtp_recipient_restrictions entries:
 
smtp_recipient_restrictions=permit_mynetworks,
                                         reject_invalid_hostname,
                                         reject_non_fqdn_hostname,
                                         reject_non_fqdn_sender,
                                         reject_unknown_sender_domain,
                                         reject_unknown_recipient_domain,
                                         reject_unauth_pipelining,
                                         reject_unauth_destination,
                                         reject_rbl_client zen.spamhaus.org,
                                         reject_rbl_client bl.spamcop.net,
                                         reject_rbl_client dnsbl.njabl.org,
                                         reject rbl_client 
dnsbl-1.uceprotect.net
                                         permit
 
 
Thanks for help!
 
Oliver
