Exchange 2013 cannot send/receive mail

This is a brand new exchange 2013 install.  Last night at 10:58 is was sending and receiving mail. This morning, it's not.

I can telnet to it, but I don't get the standard reply, I just get a black screen.

My outlook and OWA can connect and login, but all outbound mail sits in the drafts folder.

Inbound does not arrive, nor is there a bounce.

Certs are all public, and good.

I'm at a loss where to look.

This is Exchange 2013 on Server 2012, standalone install.

Thanks

Cliff

any ndr? or anything in APP logs, whether all services are running fine? what troubleshooting steps you performed till now, whether you rebooted your server, if not do it and check again.

Check your send and receive connectors to make sure that the scope tab have valid IP addresses that exists on the server. Set for all available if you can. Also make sure that if the server is a VM that it is not inheriting its clock from the VM and is syncing time with the Domain. Also make sure you have a Send connector set to use the domain * that is using MX records or a valid smart host.

Sounds like classic lack of diskspace which is stopping Exchange from processing email.

It was a rule in our firewall that one of our CCNP's wrote to manage NAT.  We took the rule out and we are good to go.

our firewall had a rule that was blocking the outbound mail.  we fixed the rule and mail is flowing.
