according the postfix restrictions i did the permitted_senders_lists and protected_recipients_lists

and i need to add a line to the main.cf of postfix

smtpd_restriction_classes = permitted_senders_list


but every-time i reload the postfix the line changes to

smtpd_restriction_classes = local_only

i need the line to be




smtpd_restriction_classes = permitted_senders_list permitted_senders_list2 ......etc

so what to do?


Thanks for any help!
