open proxy

["Joost Ernest" <jernest () chello nl>]

Hello all, 

I have a question regarding to "open proxy". We are using Domino server
as our mail server in a w2k server environment. A week ago we started to
receive a-mail from a Dutch ISP dat our mailserver has been listed in an
Open Proxy Database. As a result of this we can't send e-mail at all... 

I have started to block some ports explicitly (135, 139, 443, 1080, 
etc..) I also read some articles about this subject in which was written
that i should use Authentication for every user that wants tos end
E-mail. I know how to configure this in Exchange but i don't know how i
can arrange this with Domino server. 
Any suggestions en url's would be appreciated! 

Thanks!
