Sorry if i have not explained it correctly in the subject... (Using postfix 2.5 on debian lenny).
We are testing the "ips.backscatterer.org" setup on one of our servers and would like to understand the impact before we implement. Is there any way we can check the ips.backscatterer.org RBL for the IP, then put the message on HOLD - rather than rejecting it? smtpd_recipient_restrictions = ... check_sender_access hash:/etc/postfix/check_backscatterer, ... # cat check_backscatterer #<> reject_rbl_client ips.backscatterer.org #postmaster reject_rbl_client ips.backscatterer.org Thanks Simon
