Hi I recently transitioned from server 2003 with exchange 2003 to sbs 2011. I have transferred the mailboxes to the new server, and removed exchang 2003. However I can only receive emails but cannot send. My MX records are correctly pointing to the WAN IP of the firewall. and I have checked marked anonymous in my received connector.
I can telnet succesfully to the server on port 25 but not on port 110 and the same is true when done directly on the server.
