We have moved our Microsoft Exchange server from our local offices to an external datacentre and we now have no incoming email.
We had two DNS entries at our internet provider for "email.ourcompany.com" and "webmail.ourcompany.com" and both these have been updated to the new ip address and seem to have propagated..
From looking on the exchange server manager in the queues area, it looks as if no messages are getting to our Exchange Server.
We are able to send email out though.
We have checked the new firewall and it seems to have the appropriate ports open for the exchange server machine.
Does anyone know if we need to change anything else at all? Physically the server is the same - all thats really changed is the location and the static ip address.
We look forward to your help.
