Hi, I am trying to match my reverse DNS entry to my public mail server ip address. All incoming mail comes in fine to my cluster ip address. However, outgoing mail uses the active node's ip address (not the cluster ip address), so in effect I have two possible ip addresses I am sending email from (active + passive node). Under the SMTP Server properties in ESM the IP address is the same as the cluster ip address. Is there a way to match all outgoing mail to the cluster ip address? Any other suggestions? Thanks. Nick
This is by design. When an Exchange 2003 cluster sends SMTP it is the IP address of the Node that is used. You could configure a Front End server to send/recieve all SMTP. /Simon "Nick Stefanov" wrote in message news:7EA96C7D-677E-46CF-B3FE-C2112FFD7AD1@microsoft.com... > Hi, > > I am trying to match my reverse DNS entry to my public mail server ip > address.

Did not mention that this is Exchange 2000. Do I need a separate server to create a Frond End server?

It is the exact same behaviour in Exchange 2000. Yes you would need a seperate server for a Front End. Does your cluster go out through a Firewall? Can you do some sort of NAT that would make both the cluster Node IPs appear that they come from the same external IP address? That may solve your problem. /Simon "Nick Stefanov" wrote in message news:41B0209D-48EE-40AB-9D77-7687F0747B08@microsoft.com... > Did not mention that this is Exchange 2000.

I am having the same problem. What I did is using the CheckPoint NG to configure NAT so that all traffic originating from both nodes would tranlate to the public IP of the mail server. However, I could not get some low-end firewall(Netscreen 5XP) to do this kind of settings. :( "Nick Stefanov" glsD:7EA96C7D-677E-46CF-B3FE-C2112FFD7AD1@microsoft.com... > Hi, > > I am trying to match my reverse DNS entry to my public mail server ip > address.
