Ever though about the place where bugtraq is hosted? Also note that the IETF has nothing to do with that. > Isn't this behaviour totally antisocial from networksolutions and how > can it be stopped? Antisocial is accusing organizations. Do a dig and find out: org. 172800 IN NS TLD3.ULTRADNS.org. org. 172800 IN NS TLD4.ULTRADNS.org. org. 172800 IN NS TLD5.ULTRADNS.INFO. org. 172800 IN NS TLD6.ULTRADNS.CO.UK. org. 172800 IN NS TLD1.ULTRADNS.NET. org. 172800 IN NS TLD2.ULTRADNS.NET. ;; Received 349 bytes from 192.112.36.4#53(g.root-servers.net) in 126 ms asdf.org. 86400 IN NS gw1.solid.fi. asdf.org. 86400 IN NS gw.solid.fi. ;; Received 78 bytes from 199.7.66.1#53(TLD3.ULTRADNS.org) in 102 ms tkv.asdf.org. 1800 IN NS ns.tkv.asdf.org. ;; Received 68 bytes from 193.65.201.11#53(gw1.solid.fi) in 50 ms Now ask gw1.solid.fi where the NS is, eek a NS -> CNAME, that violates some RFC's: $ dig @gw1.solid.fi ns.tkv.asdf.org. ;; ANSWER SECTION: ns.tkv.asdf.org. 86400 IN CNAME tkvnic.tkv.asdf.org. tkvnic.tkv.asdf.org. 48291 IN A 212.16.100.33 And that host is not alive. So the MX can't be resolved, nor the A record of "tkv.asdf.org" and as such mail will bounce. Conclusion: Fix your mail setup. Instead of accusing other people of things they don't do. Greets, Jeroen
