If you want to use this list on your mail server, tell it to query the
psbl.surriel.com zone, in exactly the same way you would query
other DNSBL zones, like sbl.spamhaus.org or list.dsbl.org. Anybody is
free to use PSBL.
Exim: add the following to the acl_check_rcpt section:
deny message = $dnslist_text
dnslists = psbl.surriel.com
Sendmail: add this to the m4 file:
Postfix: add the following to the smtpd_recipient_restrictions section:
Zmailer: for late rejection at rcpt stage:
_rbl0 rcpt-dns-rbl "psbl.surriel.com"
_rbl1 test-rcpt-dns-rbl +
PSBL can also be queried from spamassassin. The following lines can
be added to /etc/spamassassin/local.cf or your own ~/.spamassassin/user_prefs:
header RCVD_IN_PSBL eval:check_rbl('psbl-lastexternal', 'psbl.surriel.com.')
describe RCVD_IN_PSBL Received via a relay in PSBL
tflags RCVD_IN_PSBL net
score RCVD_IN_PSBL 0 1.00 0 1.00
This rule is included by default in spamassassin-3.3.0+, so you do not
need to make any configuration changes to use PSBL with a recent spamassassin.
The DNSBL can be rsynced as a plain text file.
$ rsync -z psbl-mirror.surriel.com::psbl/psbl.txt .
