Is this the same thing?

See https://www.spamhaus.org/faqs/dnsbl-usage/#200 for a table
with the purpose of different lookup results.
To block xbl listed clients with postscreen, one would configure
xbl.spamhaus.org or zen.spamhaus.org=127.0.0.4

While they are the same, I recommend using the latter, so you can
benefit from caching DNS results in case the same source IP connects
to smtp and submission/submissions(=smtps) services.

I added the zen,spamhaus,org=127.0.0.[2..11 to my submission settings
in master.cf. Worked, but it blocked my AT&T mobile block. Go figure!
The discussion was "xbl.spamhaus.org" vs. "zen.spamhaus.org=127.0.0.4"
If you configured zen.spamhaus.org with different combination, no wonder you
got unexpected result.
I changed it to 127.0.0.4 to be more specific. It turns out AT&T
mobile has numbers is in the XBL database. I tried bl.spamcop.net, and
it does nothing.
No, they are in PBL database which is designed to contain home networks.
I'm not sure about spamcop, but zen.spamhaus.org=127.0.0.4 should be safe at
submission level.
Last night I logged "81 SASL authentication failed." That's about
average. Seems I have a lot of new friends.
I'm still thankful to learn more about master.cf, I had ignored it for
the most part.
