Gromox is the central groupware server component of grommunio. It is capable of serving as a replacement for Microsoft Exchange and compatibles. Connectivity options include RPC/HTTP (Outlook Anywhere), MAPI/HTTP, IMAP, POP3, an SMTP-speaking LDA, and a PHP module with a MAPI function subset. Components can scale-out over multiple hosts.
Gromox is modular and consists of a set of components and programs to provide its feature set. This repository includes a number of manual pages, for which a rendered version is at docs.grommunio.com.
Gromox relies on other components to provide a sensibly complete mail system,
The grommunio Appliance ships these essentials and has a ready-to-run installation of Gromox.
