In the message window, when trying to connect and browse an URL I got:

Contacting host: http:80
open-network-stream: http/80 Name or service not known


Now, if I set the http_proxy to leave off the "http" emacs asks me the
username/password of the proxy for 3 times and then fails with
authentication error. The same if I strip off the username/password
from the http_proxy variable.

Any other idea?

Thanks,
Luca
