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 Z-MAPI function subset.
Import is possible from PST/OST/MSG/CDFV2/TNEF, EML/ICAL/VCF, Kopano, Zarafa, and via imapsync.
Gromox relies on other components to provide a sensibly complete mail system, such as Postfix as a mail transfer agent, and grommunio-admin for user management. A webmail client interface is available with grommunio-web. The grommunio appliance ships these essentials and has a ready-to-run installation of Gromox.
