Exchange Routing Issue

[rebel4k]

I'm quite new to Exchange and I have an issue I'm hoping someone can help me with. I have set up an exchange server which can both send and receive external email. This server receives external mail by there being a rule on the router that forwards all SMTP traffic to the internal address of the server which is 192.168.0.2. The router also acts as a firewall. I have set up a second exchange server within the same domain but I'm not sure how to get external mail forwarded to this server as well because the router only allows me to create 1 rule for SMTP traffic and this rule is already being utilised by the 1st exchange server. Is this something which needs to be configured within exchange itself. I hope this makes sense. Any help would be most appreciated.

the rule should point to an internal MX record for say email.yourdomain.com and create 2 of them with same name that can resolve to each one of your exchange servers.

Thank you for the response but I'm still not sure how to configure this.. My router only allows me to forward SMTP traffic to the relevant LAN server e.g. 192.168.0.2. So if I create an Mx record (s), eg. Local.Mydomain.Com, I'm still not sure how to get SMTP traffic forwarded using the relevant Mx record. I hope I'm explaining myself correctly here.

HI,

What is the purpose of your second exchange server?

also what version of exchange are you running.

 

[rebel4k]

I am currently running Exchange 2003. I do not want to upgrade to Exchange 2007 just yet so would like to run them side by side for the moment.

HI,

What are you using the second server for?

it it to share the load of your first server?

Exchange can handle multiple email domain names, and will route mail between the two server depending on which server the users mailbox sits at.

To have two totaly seperate email servers with no routing between the two, you will need 2 external IP address and a router that can handle this. But i'm unsure why you would want this.

The second server is to share the load. I just want to be able to allow both these servers to receive external email. I currently have 1 external IP. As mentioned before I currently have a rule that forwards all SMTP traffic to the 1st server but I need to forward traffic to the second server and cannot do this as my router only allows me to create 1 SMTP rule.

HI,

If this is the case then you only need the mail to point to one server as exchange will internaly route mail between the two servers depending on which server the recipients mailbox is sat.

This depends on how you have configured your new exchange server on instalation.

Have you tried creating a new mailbox on the new server and seeing what happens?

Many Thanks

I've tried sending an external mail to a mailbox on the second server but am not receiving them. That's why I came on here to find out how to get it working. So what you are saying is that I just need to forward all SMTP traffic to the 1st server and if the users' mailbox resides on the 2nd server, exchange will route the mail? Does that mean I don't need to use Mx records? Sorry if I'm sounding dumb but I'm very new to Exchange.

When you installed the new exchange did you select the option to join the server in a existing domain or did you start a new one?

The MX records should be fine left as is, if server one is working fine.

Internaly can a user on the server send a email to a user who's mailbox is on the second server?
