nein, das findet Absender, deren MX auf 127.0.0./8 verweist, die also selbst 
keine Mail empfangen können. Ist zwar nicht das, um was es hier eigentlich 
ging, aber durchaus nützlich. Ich würde die Liste noch um ein paar andere 
Netze erweitern:

0.0.0.0/8       REJECT IP address of MX host is a bogus address
127.0.0.0/8     REJECT IP address of MX host is a loopback address
224.0.0.0/12    REJECT IP address of MX host is a multicast address
255.0.0.0/8     REJECT IP address of MX host is a bogus address

10.0.0.0/8      REJECT IP address of MX host is a RFC1918 address
172.16.0.0/12   REJECT IP address of MX host is a RFC1918 address
192.168.0.0/16  REJECT IP address of MX host is a RFC1918 address
169.254.0.0/16  REJECT IP address of MX host is a RFC1918 address
192.0.2.0/24    REJECT IP address of MX host is a RFC1918 address
240.0.0.0/12    REJECT IP address of MX host is a reserved address

195.7.77.20     REJECT IP address of MX host is a wild-card .museum
64.55.105.9     REJECT IP address of MX host is a wild-card .nu
212.181.91.6    REJECT IP address of MX host is a wild-card .nu
194.205.62.62   REJECT IP address of MX host is a wild-card .sh
216.35.187.246  REJECT IP address of MX host is a wild-card .ws

Gruß,
Gregor
