Welcome to the DNS BlackList Resource Center.
For week-by-week success and failure data for a specific blacklist, select a blacklist from the list below.
Blacklists with data available for public display:
Each blacklist detail page contains thirteen weeks worth of data, graphically represented. Each green bar represents the weekly average percentage of spam that would be blocked by use of that list. Each red bar represents the weekly average percentage of ham (non-spam) that would be blocked by use of that list. The spam and ham buckets are unique; therefore it is possible to have both a high accuracy rate against spam and a high false positive rate against non-spam.
For every 10% of accuracy, ten out of one hundred spams were successfully blocked by a given list. For every 5% of inaccuracy, one out of every twenty desired emails was blocked by a given list.
(against spam) | (against non-spam) | |
All that above you should add to your filter list...
on your mail server reject list...
Your Postfix filter could look like that:
and you could find it in file structure
*/etc/postfix/main.cf
you could edit file with "vi" or "nano"
and some where in the file you find ...
broken_sasl_auth_clients = yes
smtpd_recipient_restrictions =
permit_mynetworks,
permit_sasl_authenticated,
reject_non_fqdn_hostname,
reject_non_fqdn_sender,
reject_non_fqdn_recipient,
reject_unauth_destination,
reject_unauth_pipelining,
reject_invalid_hostname,
reject_rhsbl_client blackhole.securitysage.com,
reject_rhsbl_sender blackhole.securitysage.com,
reject_rbl_client blackholes.easynet.nl,
reject_rbl_client cbl.abuseat.org,
reject_rbl_client bl.spamcop.net,
reject_rbl_client sbl-xbl.spamhaus.org,
reject_rbl_client opm.blitzed.org,
reject_rbl_client dnsbl.njabl.org,
reject_rbl_client list.dsbl.org,
# reject_rbl_client zen.spamhaus.org,
# reject_rbl_client dnsbl.sorbs.net,
# reject_rbl_client l2.apews.org,
reload your postfix system.
you can do it like that
$: postfix reload
postfix/postfix-script: refreshing the Postfix mail system
(the response should look like that, and next like should be empty)
@ author is not responsible of list functionality above, adding is at your own risk.!
