I can't receive email from outside my internal network!!!
I am running an SBS 2008 server with Exchange 2007 configured and up until today at 9:24am - it was working properly. This server was installed brand new from Dell with a fresh install of Windows SBS 2k8 in June of this year (2010). I am an independent consultant and I rarely have to check on this client. I cannot think of anything that would have happened to make this server stop routing email messages to their inboxes. Lemme give some info (and I hope I don't forget anything!)
1. All MX records are set up and have been working properly as of June 2010
2. I am the only admin and I have not changed anything on this server.
3. Windows updates are not set to install automatically.
4. I can send from any user account on my internal network to several different emails outside of the internal network and these emails are received to my external recipients.
5. When I send email to an internal recipient from an external email, I do NOT receive an NDR message and it appears that the email is delivered successfully due to the fact that I can't tell otherwise because there is no return email of delay or non-delivery.
6. I can think of no changes made to the server that might cause this. Obviously something is going on, but I can't think of anything that I or any internal user might have done to cause this.
7. I am the only user to log into the server and access it.
8. This is small office of only 6 user accounts.
9. I CAN send email from an internal user A account to an internal user B account using the uname@domain.local email address and my user B receives the email from user A, and vise-versa. (Email can be sent internally).
10. ?!?!?!?!?!?!?!?!?
Please give me some direction! I have scoured the Internet and all problems that have been solved are not issues that I can correlate to my problem!
Thanks.

I would make sure all exchange services are running and even if they are running do a restart of all services, also check internet connectivity from server to make sure you can access an external website preferably one that hasnt been visited before as the history may load a saved copy.
You should check to your network firewalls and make sure there all the necessory ports are open. You will also need to reconfigure your connectors and run Test-MailFlow command from exchange management shell. After this run mail flow troubleshooter from tools of the exchange management console. and post the results.

Server has just been powered down and rebooted within the last half hour so all services were restarted. I have checked and all Exchange services appear to be running properly. I can access the Internet from this server and I can access this server from a remote machine using RDC - the server is available online. I have checked network firewalls and nothing has changed - all proper ports are open. I can Telnet from an outside machine into my Exchange Server over port 25. (Not exactly sure what to do from there...)
Reconfigure my connectors? What do you mean by this?

To access this solution, you must be a member of Experts Exchange.
set the logs to overwite themselves after say 30 days
also look at echange message tracking and exchange error logs
you probably would have seen the disk space error
sometimes a small exchange or server will track HD and email you at 5%

With many hours and lots of patience (and cursing), I figured it out.
It was possibly related to back pressure from the Exchange server.
