Hi,
I'm managing several mail servers running CentOS 7, Postfix and Dovecot.
SpamAssassin is filtering mail nicely, but I'm considering using RBL
(blacklists) to take some load off the servers.
General question to those of you who use RBL. Which lists do you
recommend using?
In my "reject_rbl_client" lines, I've been using:
- hil.habeas.com
- sbl-xml.spamhaus.org
- bl.spamcop.net
And in my reject_rhsbl_sender line, I have:
- ds.rfc-ignorant.org
Additionally, I've got Postgrey enabled, which does a really good job of
weeding out the spambot desktops and such.
Instead of using reject_rbl_client the better choice is to use
postscreen within Postfix. That enables the admin to set weighted
scores, not rejecting based on a single RBL.
