Hello, i have i client that im experiencing the following thing.
I have now set up a adsl solution with a fixed ip adress 126.96.36.199 and since that has been
implementet they cannot recive email anymore, they are able to send via the exchange server.
Before the adsl they had a dialup isdn connection.
The company that host their domain has set up their routers to forward all emails to the 188.8.131.52 ip adress.
What do i do on the exchange server and/or on the pix so that they are able to recive email again?
