I've have a question about the right way to configure a Receive Connector for a single Exchange 2010 Server without an Edge server.
I have a *.local internal domain name for the Microsoft domain. The default receive connector is Default EX1 and is bound to port 25 and under the "Specify the FQDN this connector will provide in response to HELO or EHLO:" I have the *.local domain. (from what you I know you don't want to mess with this).
Now I need to configure a Receive Connector for the *.com external FQDN domain so that I have a *.com domain under the field for "Specify the FQDN this connector will provide in response to HELO or EHLO:". And it will provide the correct HELO response to external queries for blacklist purposes, etc.
In configuring the second receive connector I had to configure a 2nd IP address on the same one NIC as two receive connectors can't be on the same port (port 25) with the same IP address.
This has been working for the last year in one setup but is it the correct way of doing this?
I seen examples on Microsoft's websites where there's only one receive connector but that's because they used a *.com for an internal domain name, rather than the *.local which is what I've known to use as the recommended practice.
Using a *.com domain name would eliminate the need for the second one as your HELO EHLO response field can just be your external domain name such as mail.domain.com.
I'm about to setup another network with a single Exchange server and am trying to determine if I should make it a *.com local domain or a *.local based on the above.
Thanks a bunch.
