Q:

Exchange 2010 inbound connector

We have just finished setting up an Exchange 2010 server.  So far I can send mail but not receive which I expect since we have not requested that the MX records be changed.  My question is:  Is there a way to test that inbound mail is set up correctly before I request that the MX records be changed to point to the Exchange 2010 server?
Thanks
Matt

A:

Sure, use telnet!
The flow typically goes like this:
$ telnet <ip_address> 25
> helo example.com
> mail from:sender@outside-domain.com
> rcpt to:recipient@example.com
> data
> Mail Body here
> . <enter>

After that last step, you should get a message back from the SMTP server stating whether or not your mail was accepted. If it was, then look for it to land shortly in the user's mailbox.
