Zimbra

Overview
Zimbra on OneCloudPlanet — corporate mail on your domain with calendars, contacts and webmail. Unlimited mailboxes for a fixed server price; your data stays with you, not Google.

What is Zimbra?
A Workspace/Exchange-grade mail platform: mail, shared calendars, address books, tasks and documents in one web UI. IMAP/SMTP, mobile clients and Outlook supported.

Why Zimbra on OneCloudPlanet?
Mail that actually delivers: port 25 is open (blocked in most clouds), PTR/rDNS configured for you.
Recommended configuration: 4 vCPU / 8 GB RAM / 100+ GB NVMe for 20–100 mailboxes. See pricing.
Economics: 30 seats in Google — $200+/mo; here — a fixed server price.
Data in Ukraine or the EU — your choice.
