open proxy

if you are talking about open relays the you need to make a couple of 
changes (notes 4) in the notes.ini file. you need to add the following 
lines

SMTPMTA_REJECT_RELAYS=1
SMTP_OCH_REJECT_SMTP_ORIGINATED_MESSAGES

in notes 5 you need to edit the server document to stop relays. i think 
it is on the smtp page

Hello all, 

I have a question regardin

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! 

Joost Ernest
