Hi, I have problem in sending emails from Exch 2010 to Exch 2003. I'm able to receive the emails from Exch 2003 to Exch 2010. Here is my detailed network infrastructure.
1. Exchange 2003 - IP Address - 192.168.245.xx - abc.com
2. Exchange 2010 - IP Address - 192.168.250.xx - xyz.com
Both the servers are connected to different switch and the other end are terminated to a Hardware Firewall.
I'm able to send/receive internet emails from both the Exchange server's. I have created a DNS entry so that both servers can talk to each other and a policy on the firewall too. Now the problem is am not able to receive emails sent from Exch 2010 to Exch 2003. Whereas, it works the other way round. I rearranged the policies on the firewall to ensure no blockage occurs.
I have also requested for removal of public IP Address from the email blacklist and its been done.
Can someone help me on this on where I missed out. I came to know that I can create an internal SMTP connector, so that emails are not transported via WAN. If any info required to narrow down the issue please reply.
Hey I got it working. All I did is create a new SMTP Connector on Exch 2010 and under the Network tab of SMTP Connector, I pointed the ipaddress of Exch 2003. The mails have started flowing from the both the ends fine. Anand K
