Common Questions

Correct — all Xisto Zimbra plans are flat-rate. You pay for the server resources, not the number of mailboxes. Create 10 users or 10,000 users — the monthly fee stays the same.

Yes — all plans support unlimited custom domains. Add as many company domains as you need. We configure SPF, DKIM, and DMARC records for each domain to maximise deliverability.

We configure SPF, DKIM, DMARC, and PTR records on every new server. Xisto uses clean IP ranges with good sender reputation. Deliverability to Gmail, Outlook, and Yahoo is high from day one.

Yes. Zimbra supports IMAP, POP3, SMTP, and ActiveSync. Any email client — Outlook, Apple Mail, Thunderbird, or mobile apps — connects using standard protocols. We provide setup guides on request.

Migration time depends on the number of accounts and data volume. Small migrations (under 10 accounts) typically complete within 24 hours. Larger migrations are planned in phases to ensure zero downtime. Contact us for a timeline estimate.
