Yes, I do mean ARPA records. Here is a complete example. In the postfix logs:

Apr  9 15:41:00 smtp02 postfix/smtpd[12012]: warning: 212.106.31.50:
hostname 212-102-31-50.adsl.inetia.pl verification failed: Host not
found
Apr  9 15:41:00 smtp02 postfix/smtpd[12012]: connect from unknown[212.106.31.50]

It's then rejected by zen because it's on the blacklist. I'm not using
reject_unknown_client, but I do have these postfix restrictions:

        reject_non_fqdn_sender,
        reject_non_fqdn_recipient,
        reject_unknown_sender_domain,
        reject_unknown_recipient_domain,

Here is some info about the host:

$ host 212.106.31.50
50.31.106.212.in-addr.arpa domain name pointer 212-102-31-50.adsl.inetia.pl.

And the info in the named.query.log:

09-Apr-2010 15:41:00.305 queries: client 127.0.0.1#49357: query:
50.31.106.212.in-addr.arpa IN PTR +
09-Apr-2010 15:41:01.808 queries: client 127.0.0.1#49357: query:
50.31.106.212.zen.spamhaus.org IN A +
09-Apr-2010 15:41:01.868 queries: client 127.0.0.1#49357: query:
50.31.106.212.zen.spamhaus.org IN TXT +

Can anything be ascertained from this info? Is there further debugging
info I should enable?

Thanks again for your help.
Best,
Alex
