OT: Problem with gnome.org mailing lists

[John J. Boyer]

I don't know where else to ask this question. I am subscribed to the 
orca and xml lists on gnome.org . Whenever I try to send a message I get 
an error reply like the forwarded one below. It seems to be checking my 
ip address. However, I don't have a fixed address. Others don't seem to 
be having this problem, but I can't find any information on it. It seems 
like an unnecessary precaution on the part of gnome.org .

Thanks,
John
