Lets compare backscatterer's recommended usage of their list in your
favourite MTA against your own recommendation for usage of your
hostkarma RBL in your favourite MTA:
1.) HostKarma:
deny dnslists = hostkarma.junkemailfilter.com=127.0.0.2
2.) BackScatterer:
deny senders = :
dnslists = ips.backscatterer.org
log_message = $sender_host_address listed at $dnslist_domain
message = Backscatter: $dnslist_text
I would argue, and I expect few would disagree, that you're more
likely to get a false positive from the first than the second.
Or were you ignoring the large bright red warning signs and usage
information on http://www.backscatterer.org/ ?
I'll disagree with that. A lot of the backscatterer list is sender
address verification calls. If someone is doing sender address
verification then they are filtering spam and those who filter spam are
not sending spam. On my system people doing SAV get white listed - not
black listed.
This might be more accurate:
accept !senders = :
dnslists = ips.backscatterer.org
