iis smtp nntp: Hi

When i disable the annonymous access on the SMTP VS authinthication
properties the server stops recieving Email.

I am really not sure i did two actions
1- disable the annonymous access on the SMTP VS authinthication properties
2- I am suspecting an IP address from one of my external client who is
sending Worms so i disable his IP address on the connection properties of the
SMTP VS and the server stops recieving external Email.

Why I do not know.

How to Prevent the IIS SMTP Virtual Server from Relaying E-mail Messages
1. Start Internet Information Services Manager or open the Internet
Information Services (IIS) snap-in.
2. Expand Server_name, where Server_name is the name of the server,
right-click Default SMTP Virtual Server, and then click Properties.
3. Click the Access tab, and then under Access control, click Authentication.
4. Click to select either or both the Basic authentication and the
Integrated Windows authentication check boxes, click to clear the Anonymous
access check box (if it is selected), and then click OK.

By doing so, authentication is required before access is granted to the SMTP
virtual server. In this case, if the user or computer does not successfully
authenticate, the user or computer cannot send mail to the server.

NOTE: If you click to select the Anonymous access check box and do not click
to select the Basic authentication and the Integrated Windows authentication
check boxes, all users and computers are able to access the SMTP virtual
server.

This disables authentication.
5. Under Relay restrictions, click Relay.
6. Note the options that are available in the Relay Restrictions dialog box.
By default, the Only the list below option is selected and this list is
empty. Additionally, the Allow all computers which successfully authenticate
to relay, regardless of the list above option is selected. With this feature,
users and computers that can authenticate with the server can relay through
the server. All computers are blocked except those that meet the
authentication requirements that you configured earlier in the Authentication
dialog box of the Access tab.

Note that if you allow only anonymous access, the server does not
authenticate users or computers.
7. Click Add, and then do one of the following to add a single computer,
group of computers, or a domain: • Click Single computer.
Type the IP address of the computer that you want in the IP Address box, and
then click OK.
• Click Group of computers.
Type the subnet address and the Subnet mask of the group into the
corresponding boxes, and then click OK.
• Click Domain.
Type the domain name that you want in the Name box, and then click OK.
• If you do not want to add a computer, group or computers, or a domain,
click Cancel.

8. Click OK, and then click OK

Dear Christian does this implies if i clear the anonymous i will stop
receiving email from any domain only from the internal people on my
server.
Becouse when i did so i could not receive any external email i only
recieve email locally and nothing from outside.

Thanks
