Title: RBLList and SBLList
Post by: kryptos on February 11, 2008, 09:14:18 AM

Hi All,

I have install new SME7.2 on HP proliant ML110. My problem is or i say i need you guys some advise regarding with this. On a newly installed SME7.2  the default RBLList and SBLList is the one below.

Quote

config show qpsmtpd
qpsmtpd=service
    Bcc=disabled
    BccMode=cc
    BccUser=maillog
    DNSBL=enabled
    LogLevel=6
    MaxScannerSize=25000000
    RBLList=bl.spamcop.net:combined.njabl.org:dnsbl.ahbl.org:dnsbl-1.uceprotect.net:dnsbl-2.uceprotect.net:list.dsbl.org:multihop.dsbl.org:psbl.surriel.com:sbl-xbl.spamhaus.org
    RHSBL=enabled
    RequireResolvableFromHost=no
    SBLList=bogusmx.rfc-ignorant.org:multi.surbl.org:black.uribl.com:rhsbl.sorbs.net:bulk.rhs.mailpolice.com:fraud.rhs.mailpolice.com:porn.rhs.mailpolice.com:adult.rhs.mailpolice.com:ex.dnsbl.org:blackhole.securitysage.com
    access=public
    qplogsumm=disabled

Then following from the email wiki i configure this:

Real-time Blackhole List (RBL)

Enabling RBL's
RBL's are disabled by default to allow maximum accommodation (your ISP may be on a RBL & you may not know it). You can enable RBL's by:

config setprop qpsmtpd DNSBL enabled RHSBL enabled
signal-event email-update

You can see your RBL's by:

config show qpsmtpd

You can add to your RBL's by:

config setprop qpsmtpd RBLList <rbl-list-name>
signal-event email-update

Many will argue what's best but most would agree that you can set best-practice recommended settings by:

config setprop qpsmtpd RBLList zen.spamhaus.org:whois.rfc-ignorant.org:dnsbl.njabl.org
signal-event email-update

Now my question is do still need to configure the SBLList or i have to follow the default settings? because on one our email server i have a configuration of SBLList like this:

SBLList=dsn.rfc-ignorant.org


Regards,
Rocel

The conservative settings in the wiki are safe, and you should receive all legitimate email ie
config setprop qpsmtpd RBLList zen.spamhaus.org:whois.rfc-ignorant.org:dnsbl.njabl.org
signal-event email-update


The db settings in a stock sme7.2 which are disabled by default, do include some aggressive lists, and it is highly likely you will block some legitimate email, especially mail coming from popular free systems eg yahoo, hotmail, gmail, aol etc.

Refer to this old howto for some tips, most of which is still current, a couple/few of the lists are defunct now

As you are aware there are quite a few additional lists shown in the Email wiki page.
