Microsoft Exchange can only send Externally

We are running Microsoft Exchange 2010 on a 2008 R2 Server. We have made no changes recently to the server and suddenly we cannot send mail internally or receive mail internally and we cannot receive mail externally. The only function we can do is send mail externally. I have tried to restart our sonicwall firewall that holds our send receive rules. I have also restarted the server a few times as well as restart Microsoft Exchange Active Directory Topology Service that restarts all the Exchange Services. I have not gotten anywhere with these can anyone suggest anything else?

You are still giving to little information to help you. ¿How many Exchange Servers do you have? All the rolls in the same server?. Has that machine other uses apart of mail server?
Open Exchange console go to tools and answer me with descriptions about what you see on Queue Viewer. Go through all mail flow tools looking for clues.
Check the list of accepted domains on: enterprise settings->hub transport-> accepted domains.

Can a user send a self email ?
Is the Anonymous checked on the Receive connector ?
Are all services running on the Exchange server ?
If the email is sent from External does it hit your firewall ?
Do the senders receive an undeliverable ?

Users cannot send self email
I don't know where to check for the anonymous on the recieve connector

All services are started except three manual services that don't need to be

I can't check to see if the external email hit the firewall

no undeliverable emails when trying to send.

Permissions Tab ...... if user isnt receiving self email than its something on the server.

Can you restart the server and check possible Transport or Submission service issue.

The issue ended up being no disk space on the drive that hold our datastore. I was able to find this by looking at the queue as you suggested. We had over 2000 emails in our queue with and error stating no space on the datastore. We were able to increase that size of that drive and partition and now we are able to send/receive internally and externally.

I had the same problem a few years ago. The silly think of Microsoft Exchange is that there are no warnings on the event log of the server about the server is getting short of space and I don’t know a way to make a custom notification to the email. Thanks for your points.
