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

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.
