SBS 2008 blocking port 25 - pop3 connector error
All of a sudden we stopped receiving mails in our Outlook exchange.
I have found out that pop3 connector results in an error, therefore not receiving any mails from our webmail providor.
In Event Viewer I get this message:
Cannot connect to the SMTP server 'localhost' on port 25. The error code was 0x800ccc0e. Verify that the Microsoft Exchange Transport service is running and that the Exchange receive connectors are properly configured.
Telnet to port 25 gives me: Connection Failed on both internal an external IP.
E.g. port 80 is OK.
The "Fix My Network" keeps complaining about a missing port mapping (prob. port 25)
My router forwards OK, but using canyouseeme.org results in a "Connection Timeout"
When changing the forward of port 25 to another device the connection is successfull.
So I assume that the problem must lie in SBS.
I have AVG Internet Security Business Edition 2012 installed on the server.
have tried to disable resident Shield and scanning of incomming emails, as I have disabled the Windows Firewall, but no change.
Please Help!!

I don't think we have the same error, as it seems that wirelessnut in the thread actually can get a response on port 25, but having authorisation problems.

By the way. I tried sending a mail from one exchange user to another, but that didn't reach the other exchange user either.
please reboot your server once and after reboot check for exchange transport service running or not.
ASKER
Done!
The service is not started.
which was also a symptom before I restarted the server.
I can start the service, but shortly after it stoppes again, without notice.

check out your server logs for it why its getting stops automatically and post the error log here for further discussion.

Well were back to the same error message that i mentioned in the beginning:
Cannot connect to the SMTP server 'localhost' on port 25. The error code was 0x800ccc0e. Verify that the Microsoft Exchange Transport service is running and that the Exchange receive connectors are properly configured.
The message is logged under Application and Services Logs -> Win SBS -> Mic-Win-SBS operational
It is the only message in that window. But there is a lot of them.

go to “<drive>\Program Files\Microsoft\Exchange Server\TransportRoles\data
And start the exchange transport service it will create this folder automatically again.
