Okay here is my problem. We have 3 new Servers 2008 64bit, we can't get any of them to send email thru our Exchange 2003 Server. (Relay) I have gone into Exchange system manager and made sure that in the relay restrictions that the ip address of all the server 2008 are in there. So for example in SQL you can send an email out if an event is triggered using smtp. When we do this for any other server running 2003 it has no problem relaying it through our exchange 2003 server and the person gets it inside or outside our company, but when we try the exact same thing using a server 2008 it does not work to an outside email address. Since this works with all our server 2003's and has since I have been here (6 years) it seems to be something with Server 2008 trying to relay through our exchange server 2003.
I have been told to call Microsoft on this but know this site is as good or better than they are :)
This is the error message that we get:
The mail could not be sent to the recipients because of the mail server failure. (Sending Mail using Account 1 (2009-05-04T14:06:26). Exception Message: Could not connect to mail server. (No connection could be made because the target machine actively refused it 10.216.239.70:25).
