Exchange 2010 Internal and External Mail sending and receiving problem

I have a major problem on my Exchange Server (live server). The server is not delivering mails sent from internal or external senders. I have checked the message tracking utility and only get this when sent internally to internal recipient:

Delivery Report for gunter ¿(gunter@company.co.za)¿

Submitted
2014/01/04 06:48 PM EXMAIL.comany.za
The message was submitted to exmail.company.za.

Failed
2014/01/04 06:48 PM exmail.company.za
The message couldn't be delivered.

This is from internal to external:

The message was submitted to exmail.company.za.

Failed
2014/01/04 02:05 PM exmail.company.za
The message couldn't be delivered.

Event logs aren't providing much information, so I am at a loss.

Please can someone urgently assist

I have used the Exchange Troubleshooting Assistant and it suggests that there is no problem.
I have a freaking ghost messing with my head.

Another point of concern is that the folders that contain the logs are emtpy...

Moving into a mild panic now.

Have you check that all exchange services are running and iis is running on exchange server?

I have checked that and they are running.

I have created a new database and moved all mailboxes to the new DB, but the problem remains.

I am running ESEUTIL /P on the original DB now.

Out of interest, once all mailboxes have been moved can I simply just dismount the old DB and remove it?

If the all mailboxes from old DB has been moved to new one , you can simply delete \ remove old database and in that case no need to repair old db as well

There is nothing any miracle that stops mail flow

You need to do step by step trouble shooting from scratch

For Ex:
Telnet SMTP 25 from internet to your SMTP gateway
Verify your domain MX records on public DNS. You may use tool http://mxtoolbox.com/

Also you can test mail flow end to end
http://exchangeserverpro.com/exchange-2013-test-mail-flow/
Also you need to check on SPF record for your domain is correct \ exists and public IP is not blacklisted

Here is the excellent article which may helps you to trouble shoot

I was up till 3am, then woke up at 7am to carry on scratching, after a lot of curing I think I may have stumbled on the problem. The MS Exchange Troubleshooter indicated that SMTP was running but is not functioning, I checked the SMTP agents and I suspect that my Avira Anti Spam might be the problem, I have removed it now and rebooted the server, just waiting on the server to come back up. Will keep posted.

Ok so Avira Anti Spam was cause this whole pain, one good thing that came from this is that my Exchange is running on a new DB and the old one has been cleaned of any corruption and been defraged so not an entire waste of time.
