BusinessMail 4 is a powerful Intranet/Internet email server and anti-spam system designed specifically for the business environment. It can be installed on any W95/W98//ME/W2K/XP or NT4 PC, and does not require a dedicated PC for smaller installations.
BusinessMail 4 offers single/multiple email domain support, a web mail interface, web based configuration, fully user configurable "score based' anti-spam system, user & domain aliasing, powerful routing/filtering, flexible connection scheduling, remote administration via simple emails, support for permanent connections such as ADSL, cable and others, and of course all types of dial-up connections, automatic SMTP mail collection (if you have a permanent Internet connection and an MX record) and also via POP3 from multiple pop3 mailboxes.
BusinessMail 4 can even send mail directly to internet recipients without an SMTP relay (using MX records), making it perfect for DSL, RoadRunner and other permanent connection users that are hosting their own Internet domains. BusinessMail 4 provides support for user configurable ports to allow it to connect across your network via internal or external routers, cable modems, dial-up systems or T1/T3 connections. A 2 mailbox system is only $62, a complete 5 user BusinessMail 4 email server system is $322, and more mailboxes can be added for a small incremental cost.
