cloud.core.gen.tr Webmail brings business email together with a modern interface. We built it as a contemporary alternative to classic webmail clients such as Roundcube: it is fully compatible with the open standards — IMAP, SMTP, CalDAV, CardDAV — so your data remains yours and you can migrate away at any time.
Highlights
- Modern mail experience — Three-pane layout, real conversation threading (RFC 5256), unified inbox, a fast virtualized message list and server-side search.
- Powerful compose — Rich text or Markdown, drag-and-drop attachments, autosaved drafts, send-later and automatic identity selection.
- Efficient triage — Snooze, color-coded labels, saved searches, mute-thread, bulk actions, drag-and-drop between folders and keyboard shortcuts.
- Trust badges — DKIM, SPF and DMARC verification results on incoming mail; a visual Sieve rule builder, vacation auto-responder and forwarding.
- Calendar — CalDAV month/week/day views, reminders, invitation replies (iMIP), a free/busy slot finder and birthdays.
- Contacts — Two-way CardDAV sync, vCard and CSV import, contact groups, save-sender-to-contacts.
- Nextcloud integration — Browse files, save attachments to Nextcloud, attach from Nextcloud and create share links.
- AI assistant — Smart reply suggestions and an assistant panel that follows you across mail, calendar and contacts — with enterprise guardrails such as daily usage budgets, read-only default scopes and prompt-injection boundaries.
- Instant updates — Sub-second new-mail notifications via websocket broadcasting and an IMAP IDLE listener; browser and Web Push notifications.
- API and MCP — A 67-endpoint REST API with OpenAPI docs, and an MCP server exposing 63 tools for AI assistants.
Enterprise Assurance
Keycloak single sign-on (with an XOAUTH2 bridge to IMAP/SMTP), two-factor authentication, session management and brute-force lockout are standard. For organizations with a single mail server, "company mode" gives your users a simplified experience that asks only for email and password.
It runs against the Postfix + Dovecot + Rspamd stack; the interface ships in English, Turkish and Arabic (RTL) and installs as a PWA on phones. Get started with your own domain at https://cloud.core.gen.tr.
