Exchange 2010 cannot recieve external mails, but internal and sending out is fine! Please help!!

We have a mail proxy filter in place and I can see mails are being received by our network although after I release them from quarantine it like they are being stored by the exchange server and not being released.

Can you share your email domain so I can run an SMTP test from MXToolbox?

Are all of your incoming emails getting quarantined?

If it will take long time to free disk space and you want to start the mailflow right now you can change the QueueDatabasePath and QueueDatabaseLoggingPath to another drive which has sufficient free disk space.

To chang the path go to navigate to \Program Files\Microsoft\Exchange Server\V14\Bin folder and open the file EdgeTransport.exe.config with notepad and change the same.You need to restart the MS Exchange Tranport service.

1.Check your MX records in your DNS and see where it's pointing to and then If that is good check your port forwarding.
2.Which authentication types are configured on the connectors ? Please ensure that one of them has anonymous for authentication. My personal advice is to create a seperate receive connector which has this settings.

Hey guys, firstly thanks for all of your responses. I have managed to resolve by clearing space on the server. I has a log file going out of control but have relocated it now.

I've requested that this question be closed as follows:

Accepted answer: 0 points for gpersand's comment #a39486194

for the following reason:

Overgrown log file

Overgrown log file is a cause of lack of disk space, which would result in BackPressure being applied, which several Experts have pointed to, my comment and link to my article was the first comment to mention this, with a solution.

Objecting to the intended closure accordingly.
