Is the IMC installed and viewable from the
Exchange Server Administration program?
ANSWER:
Yes. Proceed to step 2.
No. Run Setup from the Enterprise version to install; select Add/Remove,
select Microsoft Exchange Server, and click Change
Option. Select SMP/Internet Mail Connector. If you have the
standard version of Exchange Server, install the IMC from the IMC
Connector disk.
Run the Exchange Server Administration program when you finish and
configure the IMC as outlined in Chapter 11 of the Microsoft Exchange Server Administrator's
Guide.
QUESTION:
Does the IMC start?
VERIFY:
At a command prompt, type:
net start
Look for "Microsoft Exchange Internet Mail Connector." If you do not see
it, type:
net start msexchangeimc
-or-
In Control Panel, double-click Services, and start the Microsoft
Exchange Internet Mail Connector.
ANSWER:
Yes, the IMC starts. Proceed to step 3.
No, it does not start.
Has the IMC ever started successfully?
No. What error is encountered when the IMC attempts to start, and
where is the error found?
Event ID 1075 and 7003 in the Event Viewer.
Verify that the IMC computer has TCP/IP installed and was restarted.
Event ID 2140 in the Event Viewer.

QUESTION:
Has the IMC ever started successfully?
ANSWER:
No. What error is encountered when the IMC attempts to start, and
where is the error found?
If Event ID 1075 and 7003 are in the Event Viewer, verify that the IMC
computer has TCP/IP installed correctly (that is, with the correct IP address and
subnet mask) and was restarted.
Event ID 2140 in the Event Viewer.
QUESTION:
Can Exchange Server users receive messages from a telnet session?
VERIFY:
Verify that in the IMC, on the Connection tab, in Transfer Mode, either Inbound or Inbound & Outbound is selected, and set up Diagnostics Logging for
SMTP Protocol Logging; see page 576 in the Microsoft Exchange Server Administrator's
Guide.
Test for basic SMTP functionality to the IMC with telnet. For additional information, please see the following article in the
Microsoft Knowledge Base:
153119
(http://support.microsoft.com/kb/153119/EN-US/
)
XFOR: Telnet to Port 25 of IMC to Test IMC Communication
Run the Exchange Client, read the message, and verify that mail is
received. If the message is not received, try the telnet session again, and
verify that the message is sent to a valid user's SMTP address in
accordance with the intended recipients' SMTP E-mail Address property page.
QUESTION:
Can Exchange Server users receive messages from an SMTP host?
VERIFY:
In step 4 you used 153119
(http://support.microsoft.com/kb/153119/EN-US/
)
to verify that the IMC can receive mail.
Now you need to see the actual production host that is
intended to "relay," or "forward" messages to the IMC communicate with the
IMC. From this host repeat the Telnet instructions above.
Generally if there are problems telneting to the IMC from this host
there is most likely a network or protocol problem. The following steps
help verify a network issue.
At a command prompt, ping the IMC computer's IP address from
the mail host to verify connectivity. If the ping fails:
Check to see if you have the correct IP addresses.
Verify that the IP address of the default gateway is correct; type the
following at a command prompt:
IPCONFIG.exe /All |more
Make sure IP routing is enabled between physical segments.
Verify that the link between routers is operational.
After a successful ping to the IP address, try to ping the host name of the
IMC from the mail host. To find the host name of the IMC, at a command
prompt, type:
If the ping of the IP address works but the ping of the HOST NAME fails,
Domain Name System (DNS) or Windows Internet Naming Service (WINS) does not function correctly. Refer to the
Microsoft Exchange Server Administrator's Guide, and see "Adding the Internet Mail Connector Computer
to DNS" in Chapter 11. Specifically, you need to check the "A" (address record.)
Only after a telnet from the production host is successful can you address the
particulars of the production environment. Occasionally
telnet messages are successful, however, specific messages from the
production host or outbound to the production host (for example, message
with body text, message with many users on the To line, or messages with
attachments that exceed a size limit of the production host) fail. In
these cases it is necessary to use Microsoft Systems Management
Server's Network Monitor to do protocol trace between hosts.

How to Capture Network Traffic with Network Monitor
QUESTION:
Can Exchange Server users send messages to an Internet (SMTP) host?
VERIFY:
Verify that in the IMC, on the Connections tab, in Transfer Mode, either Outbound or Inbound & Outbound is selected, and set up Diagnostics Logging for SMTP Protocol Logging; see page 576 in the Microsoft Exchange Server Administrator's Guide.
Run Exchange Client and compose a message to an SMTP address (one from the
example).
Does the message leave the Outbox of the active user?
Yes, it leaves the Outbox.
Does the message get returned to the user quickly?
Yes, The message comes back. A copy is in the Sent folder.
Check the Address Space (remove/ Regen).
Disable ResolverSearchList, and refer to the following article in the
Microsoft Knowledge Base:
150969
(http://support.microsoft.com/kb/150969/EN-US/
)
XFOR: All Messages Sent Over IMC Result in NDRs
Stop and then restart IMC and message transfer agent (MTA).
No, there is no return message.
Does the message stay in the Outbox?
Yes, the message stays in the Outbox.
If the message stays in Outbox this is an MTA issue.
No, the message leaves the Outbox.
Is the message in the IMC Outbound Queue?
The details say Host Unreachable.
Verify that the IP address is correct.
Check Email Domain Button for incorrect entries.
Verify that port 25 is available and
active on the destination host using
153119
(http://support.microsoft.com/kb/153119/EN-US/
)
.
The Properties say TCP/IP timeout use netmon.
No, the message is not in the outbound queue.
Check the GWART for other installations of the
IMC. (That is, this could be a MS Mail Connector with a SMTP address
configured.)
