I believe that it's listed 'correctly', per that FAQ, for one reason:
CNAME, not PTR. SORBS *appears* to want PTRs (with appropriate TTLs).
Following up to myself (bad form!), I'm mistaken. This IP was probably
originally listed because it's in a huge swath of hostnames with generic
rDNS. I submitted a ticket to have it delisted, was rejected by the robot,
and found (in discussion w/the SORBS admin[1]) that a DNS lookup on that
IP failed:
[86400] 141.17.85.65.in-addr.arpa domain name pointer newgate.xpasc.com.
Host 142.17.85.65.in-addr.arpa query failed: Connection Timed Out
[86400] 143.17.85.65.in-addr.arpa CNAME pointer 65.85.17.143.xpasc.com.
(Interestingly, out of the whole /24, that's the only lookup that failed)
There's a 48 hour timeout before a new request for this IP can be
submitted. If this host appears in anyone's MX record, let me know - that
can push this request to a different queue.
