=====Real-time Blackhole List (RBL)=====
Enabling RBL's <br>
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 sbl-xbl.spamhaus.org:whois.rfc-ignorant.org:dnsbl.njabl.org
signal-event email-update
=====Server Only=====
Some of the spam filter rules cannot work unless the SMESERVER knows the external IP of the box. If you put a SMESERVER in server-only mode behind other firewalls, it will lose some of the anti-spam rules. For example, the rule that blocks attempts where spammers try "HELO a.b.c.d" where a.b.c.d is your external IP address.
Unfortunately, many admins believe that port-forwarding SMTP provides additional security. It doesn't, it limits the SMESERVER's ability to apply some rules.
