We have our DNS and web hosting with you - let's call it
ourdomain.co.uk for the purpose of this thread
Part of our DNS is (using a ficticous IP address):
mail (A) 1.1.1.1
MX [10], mail.ourdomain.co.uk
The
mail.ourdomain.co.uk A Record points to our Exchange Server which is in our offices
We receive email just fine, and have done for weeks
Everytime I speak to support at eUKHost, they always take one look at our DNS and say: "
mail.ourdomain.co.uk is pointing to the wrong IP address, it should be pointing to our (eUKHosts') mail server"
How can this be true? Surely the Internet won't know where to route an email destined to an
@ourdomain.co.uk email address when there's ineffect two domains with the same name i.e.:
1. ourdomain.co.uk located at eUKHost
2. ourdomain.co.uk located at our offices (SBS 2008 Server)
I have a hunch that this can be explained/resolved by:
1. Setting
mail.ourdomain.co.uk to point to eUKHost's mail server
2. Creating a
Mail Forwarder to forward email from eUKHosts' mail server to our Exchange Server
So, my questions can be summarised as:
"Have I setup our DNS (in this particular example) correctly, or have I chosen a non-standard way of doing it?"
"Should mail.ourdomain.co.uk point to our Exchange Server or eUKHosts' mail server?"
If you have a suggestion that will require me to make any changes, please spell it out step-by-step-
by-step, as you can imagine my boss is likely to be very unhappy if our emails stop working
One suggestion which won't be acceptable is if we have to setup Mail Forwards for individual email addresses - please tell me this isn't recommended
I look forward to your responses
