MsgCore as SMTP/POP3
Mail Server
This is a server program brings both SMTP and POP3 capabilities to your Windows NT and Windows 95/98. It works silently in the background so that you cannot feel it. It is compatable with any mail client compliant to SMTP and POP3 standards, such as Microsoft Outlook, Netscape Communicator Messenger, Eudora, and hundreds of mail clients in the whole world.
Features

Multiple
Virtual
Domain
MsgCore can create mail servers per IPs on the same computer. For example, if you want to create 2 different domains: domain1.com and domain2.org on the same computer ( each domain must have its own IP number(s) ), MsgCore can create 2 mail servers for these two domains so that sales@domain1.com and sales@domain2.org represent two different email boxes. Therefore, there is only one computer actually, but acts like 2 computers to all Internet users.

Dialup Connetions Traditional mail servers require leased lines to the Internet. With MsgCore, there is no need for leased line. MsgCore can dial-up to your ISP perioridically, send out-going messages out, and pick messages from your ISP's POP3 mail servers automatically. With MsgCore, the cheapest modem-based dial-up network can replace expansive leased lines.
