Hi,

I have noticed an increasing number of domains that have been
used for spam and are pointing back to 127.0.0.1. Eg:

dig mx ministre.net @ns.bsdhost.net

; <<>> DiG 8.3 <<>> mx ministre.net @ns.bsdhost.net

;; ANSWER SECTION:
ministre.net.           2D IN MX        10 localhost.ministre.net.

;; AUTHORITY SECTION:
ministre.net.           2D IN NS        ns2.ulimit.com.
ministre.net.           2D IN NS        ns.bsdhost.net.

;; ADDITIONAL SECTION:
localhost.ministre.net.  2D IN A  127.0.0.1


dig mx arf.org @ns1.nill.net

; <<>> DiG 8.3 <<>> mx arf.org @ns1.nill.net

;; ANSWER SECTION:
arf.org.                1D IN MX        20 backup.visual.com.
arf.org.                1D IN MX        10 127.0.0.1.

;; AUTHORITY SECTION:
arf.org.                1D IN NS        ns1.nill.net.
arf.org.                1D IN NS        ns2.nill.net.


Besides that is a violation of RFC:s to have a IP-address
togheter with MX record, it's also creates some problems
when the user tries to resolve the hostname.

Comments?
