1. Install some proxy on W2k AS, like ISA server.
2. You can either install your own mailing application or just mail client that will be server.
EG:
1. You can install Exchange Server and configure users to have their mail adressies. In that case you only need active connection 0-24 so people could send mail to employed and you are your own ISP, you just use aDSL services from ISP.
2. Second solution is to install mail client onto server, like WinRoute or WinGate an to create one mailbox at ISP server, like companyname@domain.com. Then, when somebody send mail to user1@domain.com and user2@domain.com your ISP will put those mails into single companyname@domain.com mailbox. When you connect to ISP you will download all mails from single mailbox and WinRoute/WinGate will read header of each mail and find out is it mail for user1, 2 or user32. In that case you do not need 0-24 connection, you can schedule internet server to connect every 30 minutes to download mail from companyname@domain.com address. For that you need to ask that service from ISP. Call them and tell them what you want. It's mail relaying feature. Maybe it's better if you are not experienced with mail servers. Create user accounts in WinRoute.
This is only list of your options.
