I use latest delegate under win2000 , for proxying news of my ISP.
I made setup like this:
dg.exe -P119 SERVER=nntp EXPIRE=100d CRON="0 * * * * -expire 100d" MOUNT="=
nntp://news.my-isp.com/" CACHE=do DGROOT="D:\delegate"
ADMIN="admin@somewhere.."
PERMIT="*:*:192.168.0.0/24,192.168.1.0/24,192.168.2.0/24,192.168.3.0/24,127.
0.0.1/32"

I have questions :
Hove to make local news group like something.org  - post will be used only
in local network - not go to my ISP?
Also for other regular news group (where post go to my ISP) is there any way
to change headers in news post like this:
NNTP-Posting-Host: my.news  , X-Complaints-To: abuse@my.. .

Im interesting for this to have fully operational news server , but I like
that is act like proxy ... download only this post which someone read ...
Thanks for any tips!
