Can you please let me know the result of these settings mentioned below: I 
think it is not working the way it is supposed to. 

Settings done: 

On the SMTP virtual server 

   Under ?Relay restriction?, I have checked ?only the list below? and I have 
given 10.123.124.x and 10.249.11.X subnet
   Also I have selected ?Allow all computers which successfully authenticates, 
regardless of above list.


With these settings it is working as follows:

1. I can relay external mails from 10.123.124.x and10.249.11.x subnets with or 
without selecting "my outgoing server requires authentication" on Outlook 

2. If i remove 10.123.124.x and 10.249.11.x from "relay restriction" (as shown 
in figure enclosed) then i cannot relay from these subnets even if i check " 
myserver requires authentication" on Outlook express. 


So i feel authentication part is not at all working. I even tried with "grant 
or deny access for specific user" option but no luck. Can some help me on this. 
I just want to allow users to realy who have valid username and password.


I am using Exchange 2003 with SP1. I actually tried to send a mail with a snap 
shot but it seems the list is not accepting it.
