Using Our Databases


    Our three realtime lists are freely exported in an RBL-style DNS zones, rsbl.aupads.org, orvedb.aupads.org and duinv.aupads.org, but you need to choose how you will get this information.

    You can use our DNS databases as showed below:
     1) Using a direct DNS lookup, that don't need any authorization.
    Below we explain about how you can use them both ways:


    1) Using a direct DNS lookup:

    A RBL-style DNS zone works with a simple principle of operation, a host address in dotted-quad form is given and its octets are reversed and a DNS address is appended, if you are using our RBL-style DNS zones, you will get anything like zzz.xxx.www.yyy.orvedb.aupads.org. Example: If your MTA gets a SMTP session from a remote host that has a IP number like 10.0.2.2, it will check the existence of anything like:
          2.2.0.10.rsbl.aupads.org       IN     A    127.0.0.2
                                      or
          2.2.0.10.orvedb.aupads.org     IN     A    127.0.0.3
                                      or
          2.2.0.10.duinv.aupads.org      IN     A    127.0.0.4
    If your MTA gets a response like 127.0.0.2, 127.0.0.3, 127.0.0.4, etc... it means that the remote host is listed in the RBL-style DNS zone and, if your MTA is configured correctly, an error response like "550 Mail from 10.0.2.2 refused: spam site. See http://www.aupads.org/cgi-bin/rsbl-lookup?10.0.2.2" will be sent to the remote host and the SMTP session will be closed after it, without any other SMTP negotiation be completed.

    NOTE for Sendmail Users: The configuration below is not recommended anymore! We strongly recommended that you use the GNU LibAntispam instead!
    We recommend that you use a MTA that supports multiple RBL-style zones lookup, like Sendmail 8.10 or above. You must create a sendmail.mc file that will be compiled using the M4 macro processor generating a sendmail.cf file that will be used by your sendmail. In the sendmail.mc file you MUST add the directive FEATURE(dnsbl,...) to add the RBL-style DNS zone files that your MTA (Sendmail) will use to verify any remote host that opens a SMTP session. You can add one or more of the directives lines below:
FEATURE(`dnsbl',`rsbl.aupads.org',`"550 Mail from " $&{client_addr} " refused: spam site.
        See http://www.aupads.org/cgi-bin/rsbl-lookup?host_to_find="$&{client_addr}""')dnl

FEATURE(`dnsbl',`orvedb.aupads.org',`"550 Mail from " $&{client_addr} " refused: open relay.
        CONSULT YOUR MAILSERVER ADMIN. See: http://www.aupads.org/cgi-bin/ordb-lookup?
	host_to_find="$&{client_add}""')dnl

FEATURE(`dnsbl',`duinv.aupads.org',`"550 Mail from host " $&{client_addr} " refused: CONSULT
	YOUR ISP. We do not accept deliveries direct from remote dialups. Use your ISPs local
	SMTP server or authenticate via POP3 first. See http://www.aupads.org/cgi-bin/
	duinv-lookup?host_to_find="$&{client_addr}""')dnl

   The extra directives below configure your MTA to consult MAPS RBL, ORBS and others realtime
lists:
   NOTE: Due to some severe circumstances, ORBS is inoperative now!

FEATURE(`dnsbl',`rbl.maps.vix.com',`"550 Mail from " $&{client_addr} " refused by blackhole
	site rbl.maps.vix.com. See http://maps.vix.com/cgi-bin/lookup?"$&{client_addr}""')dnl

FEATURE(`dnsbl',`dul.maps.vix.com',`"550 Mail from host " $&{client_addr} " refused: CONSULT
	YOUR ISP. We do not accept deliveries direct from remote dialups. Use your ISPs local
	SMTP server or authenticate via POP3 first. See http://maps.vix.com/dul/"')dnl

FEATURE(dnsbl,`relays.mail-abuse.org',`"550 Mail from " $&{client_addr} " refused - open
	junkmail relay. CONSULT YOUR MAILSERVER ADMIN. See http://relays.mail-abuse.org/
	cgi-bin/nph-rss?" $&{client_addr}""')dnl

FEATURE(`dnsbl',`relays.orbs.org',`"550 Mail from " $&{client_addr} " refused - open relay.
	CONSULT YOUR MAILSERVER ADMIN. See: http://www.orbs.org"')dnl

FEATURE(`dnsbl',`mr-out.imrss.org',`"500 Mail from " $&{client_addr} " refused - open relay.
	CONSULT YOUR MAILSERVER ADMIN. See http://www.imrss.org/"')dnl

FEATURE(`dnsbl',`dssl.imrss.org',`"550 Mail from host " $&{client_addr} " refused: We do not
	accept deliveries direct from remote dialups. CONSULT YOUR ISP. Use your ISPs local
	SMTP server or authenticate via POP3 first. See http://www.imrss.org/dssl/"')dnl
    Please, verify in the Sendmail site how to configure your sendmail using M4 macro processor compile.

    If you are using Smail-3.2.0.112 or above, you can add the configuration line below in the "config" file:
	smtp_rbl_domains="rsbl.aupads.org;127.0.0.2/32:orvedb.aupads.org;127.0.0.3/32:\
	duinv.aupads.org;127.0.0.4/32"
    If you are using Postfix-1.1 Patchlevel 12 or above, you can add the configuration lines below in the "main.cf" file: (thanks to João Carlos Mendes Luis <jonny@jonny.eng.br>)
	smtpd_client_restrictions =
		 permit_mynetworks,
		 reject_maps_rbl


	maps_rbl_domains =
		 rsbl.aupads.org,
		 orvedb.aupads.org,
		 duinv.aupads.org
    NOTE: The performace of your MTA will sensibly decrease if configure many RBL-style DNS zones!


    NOTE: Our realtime lists are freely exported by anybody who wants to use them. If any host XXX blocked a delivering mail from a third-party host that is listed here, it is because the third-party host MUST comply with the rules that the XXX's admin (not our rules) requires to a mail message can be delivered to it. We are just verifing to the XXX's admin whether a host is a spammer, open-relay or IP/DIALUP machine or not.
