The problem
Email hosting is stuck between two bad options
Complex setup
Configuring Postfix, Dovecot, OpenDKIM, and SpamAssassin by hand takes days. One wrong DNS record and your emails land in spam.
Expensive cloud
Google Workspace and Microsoft 365 charge $6–12 per user per month. For a 50-person team, that’s $3,600–7,200 a year — for email you don’t own.
No middle ground
Self-hosted means freedom but complexity. Cloud means simplicity but lock-in and recurring costs. There should be a third option.
CeyMail is the third option.

AI Screening
Inbound and outbound spam protection
Screen both inbound and outbound email with 99.2% accuracy. Cloud mode uses advanced AI to catch phishing, scams, spoofing, and spam. Local mode runs entirely on your server for maximum privacy. Outbound screening protects your IP reputation by catching compromised accounts before they damage deliverability.
- Cloud AI — highest accuracy, detects phishing and spoofing (recommended)
- Local AI — on-device model, zero data leaves your server
- Outbound screening protects sender IP reputation
- Configurable thresholds with reject, tag, or quarantine actions
- Allow/block lists and real-time screening logs
