Innosoft's PMDF Bests the Message Backbone Pack
February 22, 1999

Executive Summary: Message Backbone Switches
At most companies today, e-mail is an essential business tool. Unfortunately, as e-mail grows in importance, the management tools within most popular messaging systems lag behind. The ugly truth is that overseeing message flow between disparate e-mail systems remains a difficult task. Without the help of a true enterprise backbone, e-mail managers are left with a dilemma. They must rely on SMTP connectors to shepherd mail between disparate messaging products and face occasional reliability problems.

Enterprise backbones solve the problem of linking e-mail systems. Our Editor's Choice, Innosoft International's PMDF, has the strength and security to talk directly to the Internet and other insecure networks, providing the protection and control that internal mail networks need. PMDF also has the gateways, connectors, adjustments and conversion capabilities needed to bring the entire e-mail universe together---with a single point of control, configuration and monitoring.

Like PMDF, Control Data's Mail*Hub is mature, stable and has all the knobs an e-mail manager needs to tune a backbone and keep the messages flowing. ISOCOR's NT-only approach has its place, particularly in an enterprise with distributed switches sharing a common directory but its architecture is less flexible. Wingra's Missive is aimed at the migration market. As a migration tool, it's without peer.
