Dear Exchange experts,

Please help..

I am running exchange server 2k. Our server is getting spam emails and relaying through our server. I have following settings:

Access Tab - Relay section on SMTP server.

Select which computers may relay:
- only the list below
- Checkbox: Allow all computers which successfully authenticate:     checked   ON

Access Tab - Authentication section

All three checkbox checked ON (Anonymous access, Basic, Integrated windows)
(I followed: http://www.msexchange.org/tutorials/MF005.html)

Please tell me... Is my server open relay????????????

If not, then why spammers connect to server?? they connect and denied but then it is eating up CPU..... Also I am running GIF MailEssentials and have all rules setup.. This one is also eating lot of memory...almost CPU maxed out (100%)...

My boss says, he wants that all spammers trying to relay their emails, should not even be allowed to connection to SMTP server.. How can I perform this???

Please help..

Check out this link:
http://www.no-spam-today.com/

That product will sit between your Exchange Server and the Internet and prevent the spammers from connecting.  If your Exchange Server is overloaded, you can even use another server to do it.

If you want to block them from connecting to you at all, you'll need to block them at the router, but that will be difficult to maintain because of all the spammers out there, and they use different IPs to avoid being blocked.

Hope that helps,
