EXCHANGE 2003 relaying mail..HELP
MY EXCHANGE 2003 mail server seems to be relaying mail....
I have of course checked the relay restrictions of the virtual SMTP server properties, it is set to allow only the list below, which is empty.
Ive done a test at www.relaycheck.com and have found it to be an open relay.
Im now added to a couple black lists and im totally lost
500 points for you help...ASAP

If relay is off on the SMTP VS, then most likely you have an SMTP connector in place thats allowing relay. Open the properties of your SMTP connector and go to the address space tab. There is a check box at the bottom to allow relay to these domains. If that is checked, and the address space is *, then relay is on. Simply uncheck the box to turn off relay.

I have nothing listed in my connectors....only the defailt virtual smtp server under protocols
What is domain name or IP address in question?

I just tested that IP and got unable to relay. I also went to relaycheck and tested your server and the only relay tests that passed were relays to your own domain name (which is expected). If you are being relayed off of then the user doing it is authenticating. This ususally means either a weak admin password or an enabled guest account. Try disabling guest and changing your admin password.

I too could not get it to relay...from any where i tested it...yet we have been added to to lists...
yet if you go here , and put our ip in we come in two different lists

Passwords eh ?
Ya thats what i was thinking too...passwords etc etc...ill give that a try...
In the current sessions tab under SMTP virtual servers ....should i ever see any session in there?
If i do are these the sessions that are spamming ?
How do we find out who or what account credentials are being used to connect to the mail server from out side of the LAN and is sending mail ?
SO many question i know...but i have lots of points to hand out :)

Looks like i found it....after enabling full logging i could see that they were sucessfully logging into the mail server using the webmaster account.
