# Edit the configuration document for the server.
# Click on the following menu tabs, Router/SMTP -> Restrictions
and controls -> SMTP Inbound Controls.
# Scroll down to the "DNS Blacklist Filters" section
and enable it.
# Enter the Blacklist sites (i.e. rbl.orbitrbl.com, sbl-xbl.spamhaus.org).
# Change the desired action (Log only, Log and Tag or Log and
reject).
# If required, enter a custom SMTP error message (i.e. Your
host %s is in the RBL black list - visit this URL for removal

Exim 4.x.
------------
Exim 4.x is a lot more configurable and hence
there is more detail to add...
These entries are normally added to the acl_rcpt
ACL in the exim.conf file. The default/example exim configuration
should contain an example similar to these.
To deny access, using a normal DNSBL with TXT
records.
deny message = Access denied - $sender_host_address\
listed by $dnslist_domain\n$dnslist_text
dnslists = rbl.orbitrbl.com
This will produce a response similar to the following:
550-Access denied - 127.0.0.2 listed by rbl.orbitrbl.com
550 Test entry.
To add an X-Warning header so that users can
filter:
warn message = X-Warning: $sender_host_address
listed by $dnslist_domain
log_message = Listed by $dnslist_domain
dnslists = rbl.orbitrbl.com
iPlanet Messaging Server 5.x
---------------------------------
Chapter 10 of the Admin Guide ( http://docs.sun.com/source/816-6009-10/filter.htm#22145
) for iMS 5.2 details the 2 ways of stopping spam with the RBL
DNS block list. The first (and the recomended way) is to add
a mapping table rule such as:
PORT_ACCESS
*|*|*|*|* $C$|INTERNAL_IP;$3|$Y$E
TCP|*|25|*|*\
$C$[<server_root>/bin/msg/imta/lib/dns_verify.so,\
dns_verify_domain_port,$1,rbl.orbitrbl.com.]EXTERNAL$E
ORIG_MAIL_ACCESS
TCP|*|25|*|*|SMTP|*|tcp_local|*@*|*|*\
$C$[<server_root>/bin/msg/imta/lib/dns_verify.so,\
dns_verify_domain,$1,rbl.orbitrbl.com.]$E
This will block connections on receiving a 'RCPT
TO:' request. Alternatively you can configure the dispatcher
(using dispatcher.cnf) as follows:
[SERVICE=SMTP]
PORT=25
!...rest of normal options...
DNS_VERIFY_DOMAIN=rbl.orbitrbl.com
DNS_VERIFY_DOMAIN=sbl-xbl.spamhaus.org
!...etc...
The latter case, the incoming connection will
be rejected at the banner. This is how the RBL SMTP proxy server
works by default. It's disadvantage is some clients (incoming
connections from servers are considered clients to) ignore the
554 banner as a PERMANENT fail and keep trying to resent until
the message times out.
Microsoft Exchange 2000/2003
-----------------------------
First enable message filtering on your SMTP
Virtual Server:
Look up Microsoft support article number 261087. http://support.microsoft.com/default.aspx?scid=kb;[LN];261087
Then:
1. In System Manager, expand the Global Settings container in
the left pane, right-click Message Delivery, and then click
Properties. To expand a container, double-click the container
or click the plus sign (+) to the left of the container.
2. Click the Connection Filtering tab, and then modify the desired
settings.
