Help connecting two exchange domains on same LAN without internet

Help connecting two exchange domains on same LAN without internet

Help connecting two exchange domains on same LAN without internet

(OP)
I am trying to connect two different exchange domains on

the same LAN without internet. I will include basic

information below. My question is this network is not

connected to the internet so how can we send mail to

each other? From what I read it looks like we need to

configure SMTP send connectors and use MX records? We do

not use a smart host.

I tried setting up the SMTP connector and MX

records but it seems I am missing something because it

is not working. From what we know are firewalls are not

blocking SMTP. Do I need to create a MX record for only

my mail server in my DNS or do I need to create a link

to his mail server also in my DNS or does he only create

the MX record for his own in his DNS? It seems I need a

correct combination of settings in the exchange server

and DNS but could use some assistance on what that might

be.



My Info:

Windows Server 2008 R2

Exchange 2010 (updated)

Exchange Server name: myexchange (using generic names

and IP)

Domain: mydomain.com

FQDN: myexchange@mydomain.com

IP of Exchange server: 192.168.1.1

Their Info

Windows Server 2008 R2

Exchange Server name: theirexchange (using generic names

and IP)

Domain: theirdomain.com

FQDN: theirexchange@theirdomain.com

IP of Exchange server: 216.168.1.2
