Exchange 2010, No inbound mail

So,

Running exchange 2010.

There is no inbound mail and no NDR gets sent.

There is no queue for inbound that I see in the exchange console.

The queue file itself is growing, but no delivery occurs.

Allow ann. is on for the connectors ...

Please visit www.canyouseeme.org on your 2010 server and test port 25 for incoming mail.
If it is a bad response - your server is not configured to receive on port 25, or your firewall is not open / forwarded properly.

port is open.

The mail arrives. Even if I telnet in I can send mail, it just never gets to the mailboxes and never sends an NDR

So,

Found the problem. The mail wasn't even getting to EXCHANGE!

When we removed the last db from our 2003 SBS (exchange public)_  it freaked out and tried to take control of all the mail.

When it did this it apparently changed the SMTP Service to on, which too control of inbound mail from then on. The mail was reaching the server, just the wrong service was listening.

Thanks for all the help!

Microsoft SBS 2011 - Outside email not getting to users though they could send out and to each other on the .local addresses.

This post helped me solve my issue.  Actually the link for the website https://testexchangeconnectivity.com saved the day where the SMTP testing showed that there was a low space storage issue on my server's Exchange partition.  3+ gigabytes was somehow not enough free space and email was not being delivered.  After clearing some files and bringing up the free space to 40+ gigabytes the mail flowed smoothly.  I have seen this problem with SBS 2003 but with far less free space triggering the issue.

OK, got it.

I created a limited access test user as suggested (hidden) for the purpose of testing.  I changed the password and disabled it when I was done, keeping it handy for future use.
