whois.6bone.net refuses connections

[Michal Ludvig]

Hello,
I wanted to add new objects to 6bone registry, but whois.6bone.net refuses
connections on smtp port 25 while sending e-mail to
auto-dbm@whois.6bone.net. I've also tried auto-dbm@isi.edu, which is
several time ment on http://www.6bone.net/RIPE-registry.html, but in this
case I got no reply within almost 12 hrs. 
I know this is not the right place for complaining, but I dont know any
better ;-) Maybe someone who could fix it or help me in another way would
read this mail too.

Have a nice day

Michal Ludvig
