Open-Xchange and Pagkugi

Operator-managed webmail, calendar, and productivity platform.

At a glance

Browser-based mail with server-side Sieve, a unified inbox, contacts, tasks, calendar, documents, and optional PGP/S/MIME through OX Guard.

Where Pagkugi differs. A server-centric, operator-owned groupware platform rather than a local Maildir client; Pagkugi keeps mail local and treats it as text.
