How it connects

Portfolio advantageEngage Mail keeps an organization’s mail on a server it runs, and serves it to webmail, to mail apps over standard protocols, and to Fusion Engage’s Mail module. Engage Server is planned to sign people in and bring mail into the same connection as Engage’s calls and chat.
Diagram, not a screenshot: webmail and mail apps connect to Engage Mail, whose parts are domains and DKIM, mailboxes, folders and search, rules and the vacation responder, the delivery queue, and Mail Admin, and which exchanges mail with other mail servers over SMTP with TLS and serves Fusion Engage’s Mail module through Engage Server

What Engage Mail brings together.

WHAT IT ENABLES One mail system for an organization’s domains, its webmail, and its mail apps. Engage Mail is in development and already carries real mail on Fusion’s own server, where the mail server, webmail, and Mail Admin run today. It is not yet available to customers. The image is a diagram, not a screenshot.
