Some old Webone addresses ceased to reverse resolve not long ago. This is
causing problems with sending e-mails to those sites that insist on
accepting e-mail only well-behaved hosts only. The particular address
above is a part of a /23 block belonging to Webone:

whois -h whois.apnic.net 203.29.87.1
% [whois.apnic.net node-1]
% Whois data copyright terms    http://www.apnic.net/db/dbcopyright.html

inetnum:      203.29.86.0 - 203.29.87.255
netname:      WEBONE-AU
descr:        WebOne Pty Ltd
descr:        PO Box 603
descr:        Mitchell
descr:        ACT 2911
country:      AU
admin-c:      TT20-AP
tech-c:       TT20-AP
mnt-by:       MAINT-AU-WEBONEINTERNET
changed:      tim at webone.com.au 20020904
status:       UNSPECIFIED
source:       APNIC

etc.

The absence of delegation of 29.203.in-addr.arpa is no problem if there is
delegation of 87.29.203.in-addr.arpa, but both are absent.
