I believe that it's listed 'correctly', per that FAQ, for one reason:

[romer@toro mail]$ dig 142.17.85.65.in-addr.arpa

;; QUESTION SECTION:
;142.17.85.65.in-addr.arpa.     IN      A

;; ANSWER SECTION:
142.17.85.65.in-addr.arpa. 86265 IN     CNAME   email.xpasc.com.


CNAME, not PTR. SORBS *appears* to want PTRs (with appropriate TTLs).
