build me a E-mail forwarding System

We need a software in i need to connect that to domain and create 'n' number of E-mail addresses and we want to forward all the mails which come to those E-mail to two of the E-mail addresses (both can be changed further.) IN SOFTWARE REQUIREMENT 1. we need an area in which we can insert name and in that name should automatically connect through Domain eg: ("Abhishek"@[login to view URL]) 2. we need to see how many people are there. 3. need to forward mails which come on our created mail id on Two E-mail Id's. (these both can be changed further.) 4. need to change the addresses on which E-mails are forwarding. Need a great Interface for front-end. Points to be remmember We need to forward emails on two mail id's , from in these Two mail Id : 1 should only be inserted in back-end. even we only need to add option of adding 1 mail id only.
