I want to test SMTP on a new builded Ex server. After performing open command, lost connection. Please see the figure1 following.
the environment is that:
Exchange 2007 SP3 with CRR on Win2003 SP2.
Telnet on Workstaion which is Win7.

On one of nodes, Doing it gets same message:
connecting to mailcrr.test.local... Could not open connection to the host, on port 25: Connect failed

Hi George,

Thank you for choosing exchangecn. Per my knowledge, SMTP service is provided by Hub Transport Server in an Exchange 2007 Org instead of mailbox server.

Please confirm that the server you want to telnet on Port 25 provides such service.

Got it.
Thank you very much!

Hi,

Now, I can use Telnet. But, it say "500 5.3.3. Unrecognized command" after put both MAIL FROM and RCPT TO:
Both emailresses are available.
I use telnet on my Win7 Workstation, but on a Hub server, Is it a problem?

Thanks!

Please kindly be informed that you can't use the backspace key after you have connected to the destination SMTP server within the Telnet session. If you make a mistake as you type an SMTP command, you must press ENTER and then type the command again. Unrecognized SMTP commands or syntax errors result in an error message that resembles the following:
500 5.3.3 Unrecognized command

Thank you for your response.
Now, I have now problem:

I logon as domain administrator on a win2003 r2 server, then run Telnet,  and perform Mail From:administrator@test.local
But, get error message:
"530 5.7.1 Client was not authenticated."

try another email address, same error info.
then try: set ntlm before open command, get same error result.

What is the problem?

Thank.

No body knows?

Hi George,

I suggest you run the following command in Exchange Management Shell to grant anonymous access on the receiveconnector:

Set-ReceiveConnector -Identity "Default <ServerName>" -PermissionGroups "AnonymousUsers"

( PermissionsGroup --> PermissionGroups )

I'm so sorry. After run this command a few time, always get same error message:
The operation could not be performed because object 'hub-10-174.test.local' could not be found on domain controller 'dc2.test.local'.

Here hub-10-174.test.local is my hub's FQDN, also try "default Hub-10-174", "hub-10-174" and its IP address. get same error message. 

After double check it in DC, DNS by nslookup and ping it, all of them no any problems. So, I don't know where the issue is.

Thansk.

George

Do this:

Get-ReceiveConnector |FL Identity and copy the value printed on the screen.

Set-ReceiveConnector -Identity <the value that you copied> -Banner "Put the string here"
