Question 1

Is CeyMail really free?

Accepted Answer

The Community tier is free forever — 2 domains, 5 mailboxes, no credit card required. Paid tiers start at $49/month for teams that need more capacity, DKIM management, AI spam screening, and email support. The Business tier adds AI-powered log analysis, audit logging, and REST API access.

Question 2

What servers does CeyMail support?

Accepted Answer

Ubuntu 22.04+ and Debian 11+ on any VPS with at least 512 MB of RAM (1 GB+ recommended, 2 GB+ for AI screening). Works on DigitalOcean, Hetzner, Linode, AWS EC2, or your own bare-metal hardware.

Question 3

Will my emails actually reach inboxes?

Accepted Answer

CeyMail auto-configures DKIM, SPF, and DMARC, then generates the exact DNS records you need to copy into your provider. Proper authentication gives your domains the strongest foundation for inbox delivery. Deliverability also depends on your IP reputation, domain age, and sending practices — the dashboard includes IP reputation monitoring and blacklist checking to help you stay on track.

Question 4

Can I migrate from Gmail or Outlook?

Accepted Answer

Yes. Standard IMAP clients like Thunderbird or imapsync can transfer existing mailboxes to your CeyMail server. Once migrated, your users point their email clients to the new server and keep working.

Question 5

What happens if I cancel my subscription?

Accepted Answer

Your mail server keeps running — Postfix and Dovecot never stop. Existing domains and mailboxes stay configured and continue sending and receiving email. At the end of your billing period, the license downgrades to Community and paid features (AI spam screening, AI log analysis, DKIM management, queue monitoring, in-dashboard software updates) become unavailable. You won’t be able to add new domains or mailboxes beyond Community limits, but nothing existing is deleted or disabled. Re-subscribe anytime to restore full access.

Question 6

Do I need Linux experience?

Accepted Answer

Not for daily operations. One command installs everything, and the web dashboard handles day-to-day management — domains, users, aliases, DKIM keys, mail queues. You will need SSH for the initial install and for periodic server maintenance like OS updates and software upgrades.

Question 7

How does CeyMail compare to Mail-in-a-Box?

Accepted Answer

Both offer one-command installation and DNS record generation. CeyMail adds AI-powered spam screening, AI log analysis, supports both Ubuntu and Debian, and provides commercial tiers with role-based access control, delegated domain admins, and dedicated support. Mail-in-a-Box is fully open-source, supports Ubuntu only, and is designed as a single-server, all-in-one solution with no paid plans.

Question 8

Is my email data private?

Accepted Answer

CeyMail runs on your server and all email stays on your infrastructure by default. There is no analytics on message content and no telemetry beyond anonymous version checks. AI screening offers two modes: Cloud mode sends message content to a cloud API for the highest detection accuracy, while Local mode runs an on-device AI model so nothing ever leaves your server. You choose the privacy/accuracy trade-off that fits your needs.

Question 9

What does AI log analysis do?

Accepted Answer

AI log analysis (Business tier and above) periodically reviews your Postfix, Dovecot, and OpenDKIM logs using Google Gemini. It detects authentication failures, delivery problems, DNS misconfigurations, and security anomalies — then surfaces a severity rating, specific issues, and actionable recommendations in the dashboard. Analysis runs automatically every 4 hours and can be triggered manually. You provide your own Gemini API key in Settings, so log data goes directly from your server to Google — never through CeyMail servers. No other self-hosted mail server offers built-in AI log analysis.
