A friends ISP has started blocking port 25 inbound and outbound. We both run E2k3 servers. I'm trying to help him out until he can get his new provider online (about 3 weeks) What I want to do is accept his email and relay it to his exchange server on a different port but I consistently run into a problem.
I have a single static IP assigned to me. This IP currently handles email for 6 local domains. I've added his domain to the Default recipient email policy and unchecked the box "This Exchange Organization is responsible for all mail delivery to this address." (If its checked I get a no such user NDR) I've also changed his mx record to point to my server. I created a second SMTP virtual server with a different port number (4321) and new private IP address with windows authentication and anonymous authentication. (no basic authentication.) Since I do not expect email inbound on this ip & port it should not be an issue to use a private ip that is not NAT'd inbound through the firewall. I created a connector and told it to use the new SMTP virtual server for a local bridge head. I have it set to "Forward all mail through this connector to the following smart host" and entered his smtp's FQDN. On the Connectors address space tab I have "Allow messages to be relayed to these domains" and I added "hisdomain.com" to the address space. ( this part isn't crystal clear, I used hisdomain.com but I'm not sure if it should be @hisdomain.com or [EMAIL PROTECTED] ) Any email sent from me to him gets there just fine but email from the outside gets a NDR "Relay not allowed". external Email comes into port 25 to my default virtual server and this seems to be where the relay problem is. I want to accept email for his domain on port 25 and relay it to his exchange server on port xxxx. I only have one public ip address that serves 6 other domains already. I have a full private class C behind the firewall. Am I missing something? Is this possible. Again if I send the email from my system it gets to him fine but when email comes in via my default SMTP virtual server my server sends a NDR relay not allowed.
