From Newsgroup: comp.sys.mac.system

We are using a proxy server to connect to the internet.

Whenever we are on the proxy, I can read from Google
newsgroups, but I can't post to newsgroups using all three
browsers, Safari, IE & Netscape.

I get the error in Safari as "Posix error 60" and on IE
as Connection Failed.

I don't have this problem when I am using a windows machine
using proxy on the same network using IE or Netvigator.

Could someone tell me what causes this problem and how
we could solve this?
