Utilization of the Sago Networks Real-time Block List

Sago Networks welcomes anyone to utilize our RBL. Please understand though that the most efficient use will be gained by only Sago Networks customers. In order to use the block list, you must either be using SpamAssassin, or you must be using mail server software that supports Real-time Block Lists. Most current mail softwares support this feature. As every mail platform & software are different in configuration, this page will only address configuration of a Qmail server. If you run mail software different from Qmail, but are unsure how to go about configuring our RBL, please file a support ticket with us so we can assist you. Please note that our ticketing system is exclusively for Sago Networks customers.

Qmail & QmailRocks

These instructions are written specifically for QmailRocks, but should apply towards any Qmail server with rblsmtpd installed.

Pre-requisites:

• Must be running Qmail or QmailRocks with tcpserver
• /etc/resolv.conf must list either 66.118.170.2 or 66.118.170.3 as the primary resolver
  This pre-requisite is required as the RBL is processed through our DNS cluster. If you are running your own bind, you'll need to add the following entry in your named.conf:
  zone "rbl.sagonet.com" IN { type forward; forward first; forwarders { 66.118.128.53; }; };

Configuration

• Edit the /service/qmail-smtpd/run file and look for, and edit the following section:
  /usr/local/bin/tcpserver -v -R -l "$LOCAL" -x /etc/tcp.smtp.cdb \
  -c "$MAXSMTPD" -u "$QMAILDUID" -g "$NOFILESGID" 0 smtp \
  rblsmtpd -rrbl.sagonet.com -rbl.spamcop.net /var/qmail/bin/qmail-smtpd mail.sagonet.com \
  /home/vpopmail/bin/vchkpw /usr/bin/true 2>&1
• Note that to add our RBL, or any other, you'll need to simply add a -rHOSTNAME after the rblsmtpd. You'll want to replace HOSTNAME with the hostname of the RBL you are adding
• Sago Networks RBL has a hostname of: rbl.sagonet.com
