New Domain Pointer with email ...

Hi, here is our situation ...

We have our controlling domain hosted by discountAsp, and it needs to remain the master domain. However, our organization has merged and we have therefore acquired another domain, which we have already setup to point to our root and everything is working fine.

Our problem is that we also need to have all the old domain email address to work, at the very least to forward to our main current addresses. I know the pointer option with DiscountAsp does not offer this, but we are hoping for some type of solution. We have an account with the service called Dotster, and they offer email forwarding, but the way they do this would require changing the name servers for the domain, which would simply flip our problem: the emails would work, but not the website.

Any suggestions, advice, links, etc. is greatly appreciated.

Many thanks
