strange blocking behaviour with zen.spamhaus.org

[Harondel J. Sibble]

Anyone using zen.spamhaus.org rbl in MS and at the MTA level, noticing 
weirdness over the past say week or so?

Here's a couple of MTA level examples I've been seeing

    Feb 11 06:07:14 ranger1 postfix/smtpd[13327]: NOQUEUE: reject: RCPT from 
    alias8.phx2-aud-mta-out5.cnet.com[216.239.122.68]: 554 5.7.1 Service 
    unavailable; Client host [216.239.122.68] blocked using zen.spamhaus.org; 
    from=<newsletters at zdnet.online.com> to=<zdnet at pdscc.com> proto=ESMTP 
    helo=<alias8.phx2-aud-mta-out5.cnet.com>

    Feb 11 07:56:19 ranger1 postfix/smtpd[16391]: NOQUEUE: reject: RCPT from 
    lists.freeswitch.org[198.22.64.215]: 554 5.7.1 Service unavailable; Client 
    host [198.22.64.215] blocked using zen.spamhaus.org; 
    from=<freeswitch-users-bounces at lists.freeswitch.org> to=<help at pdscc.com> 
    proto=ESMTP helo=<lists.freeswitch.org>

These are from mailing lists primarily, and if I check the ip address noted 
in the mxtoolbox blacklist check or enter the ip at the spamhaus site, there 
is no listing, WTF????
