Suggestion Please .... Some penis enlargement drug seller
is using my SMTP to spam people I have to stop my default
SMTP service then users on my websites can't get any mails...

Please Help.

tweak your SMTP server settings (under connection properties and relay properties) within your microsoft smtp server setup, in your IIS management console.

make sure you are allowing only localhost to connect and relay though, if this smtp server is used only for SMTP

people are stupid, there are a ton of them on the internet always trying to find an open relay.

good luck

- Open up the Internet Services Manager, and expand the tree on the left.
- Right click the "Default SMTP Virtual Server" and select "Properties".
-On the "General" tab, set IP address to "(All Unassigned)" and then click "Advanced" next to it.
- Select the "(All Unassigned)" entry in the "IP Address" column, click "Edit", change the port to 26, then click OK and OK again.
- You're now back to the "General" tab. Change to the "Access" tab.
- Click "Authentication", disable "Anonymous Access", then click OK to return to "Access" tab.
- Click "Relay". This opens the "Relay Restrictions" dialog.
- Make sure the "Only the list below" radio button is selected.
- Add to the list all the actual IP addresses of the local computer, and add 127.0.0.1 as well.
- Click OK to return to the "Access" tab. Change to the "Messages" tab.
- On this tab, you can set any parameters you see fit. Remember that theseoptions are only going to effect mail sent via CDONTS, so there is no need to restrict it much. If you want, use the "Send copy of Non-delivery report to" field
- Change to the "Delivery" tab. Set the parameters on this tab to whatever you see fit. Then click "Outbound Security".
- Select the "Anonymous Access" radio button, then click OK to return to the "Delivery" tab.
- Click "Advanced". Set the maximum hop count to whatever you see fit. The "Masquerade domain" field should be blank, and both the "Fully-qualifed domain name" and the "Smart host" fields
should contain the fully-qualified DNS name of your server - e.g.
hostname.yourdomain.com (or mail.yourdomain.com). Make sure that the "Attempt direct delivery before sending to smart host" is NOT set. Click OK to return to the "Delivery" tab.
- Click OK again to close the "Default SMTP Virtual Server Properties" dialog and return you to the Internet Information Services window. Close the window.

Hope that helps!

Wow... Thanks all, especially Mike for the time

I haven't try it yet but think it will work... :)

Thanks again...
