I have a cable modem to my ISP and then on my side I have a router connected to it. Now my router is running dhcp client to the cable modem and dhcp server to my network. It also is the DNS server for my network. I want an email server to periodically download my email from my ISP and be able to view my email from any computer in the house. Also I would like it to keep my wifes email and my email in separate mailboxes. We do have separate accounts. Please let me know. Thanks
