Dear,
we use blacklists as a first defense against spammers. We have hese
lists at our postfix server:
reject_rbl_client pbl.spamhaus.org,
reject_rbl_client list.dsbl.org,
reject_rbl_client bl.spamcop.net,
reject_rbl_client safe.dnsbl.sorbs.net,
reject_rbl_client cbl.abuseat.org,
Since the end of May blacklisting is performing worse. Is there an
explanation for this?
Of course.
Read: http://dsbl.org/
Remove list.dsbl.org
Replace pbl.spamhaus.org with zen.spamhaus.org
Remove cbl.abuseat.org, which is included in cbl.abuseat.org
You mean cbl.abuseat.org is included in zen.spamhaus.org.
