Hi there,
I'm currently running Symantec Messaging Gateway 10.6.4-3 using the VMware ovf deployment virtual appliance. This product is currently in 30 day evaluation and I'm trying to get the product tested and up and running before I load of our domain and users onto to it. I've tried raising a support case with Symantec but they will not help without a support contract and I've explained that I'm not buying a support contract for a product that I can't get to work in evaluation mode.
I've got the SMG configured with 2 NIC's, the first NIC has an external IP address (212.**.***.***) and the second NIC has an internal IP address (10.10.254.80). At the moment I'm only trying to get the SMG to route inbound mail coming in on my external IP address which should be scanned and then passed onto my Exchange server port 25 which sits on internal IP 10.10.254.10.
I have the domain configured within "Protocols --> Domains" and I can see that it says "Destination Routing: Host: 10.10.254.10:25".
When I send test emails through to the SMG, I can see that messages are being accepted on the external NIC, and in the "Message Audit Log" it shows "Deliver message nomally".
The problem I have is that all inbound mail sits in the "Message queues" and never gets relayed automatically to my internal Exchange server. I can see in the "message queues" page, each test email displays the correct route for each domain and I receive the error message for each email "421 4.4.0 [internal] Failed to connect: no mail servers for this domain could be reached at this time".
Eventually, after a few days this error changes to "451 4.4.1 [internal] Connection was not attempted: domain is marked down (too many connection failures)".
Initially I thought my Exchange server must be blocking connection or rejecting messages, but if I manually put the Exchange IP address into "New route" and then manually click "Reroute All", all emails are successfully delivered to the exchange server and appear in the test mailbox.
I've also used telnet from the command line on the SMG and sucessfully sent test messages to the Exchange server, these messages were also sucessful.
If I give my exchange server an external IP address and then tell SMG to route messages to the exchange server over the external NIC, messages are getting delivered to Exchange. Unfortunately I don't have enough spare IP addresses to do this permanently, mail has to route internally to my exchange server, automatically.
Maybe I'm missing something here, but I would appreciate any help with this before I spend a ton of money on licenses.
Kind regards,
Peter
