Hosting, filtering and deliverability in one service
DiwanMail runs the whole path of your email: receiving, storing, filtering, signing and delivering — with the controls to manage it yourself.
Professional email on your own domain
Create mailboxes for every person and team, add aliases like sales@ and info@, and give each mailbox the storage it needs.
- Webmail with threaded reading, search, contacts and autocomplete
- Works with Outlook, Apple Mail, Thunderbird and phones over IMAP and SMTP
- Server-side filters and vacation auto-replies
- Per-mailbox storage limits with usage shown to every user
Every message checked, in both directions
Incoming mail is filtered before it reaches your inbox. Outgoing mail is checked before it can hurt your domain's reputation.
Virus & malware scanning
ClamAV scans every attachment. Infected messages are refused, not just tagged.
Spam filtering
Rspamd scores content, links, sender reputation and authentication. Users train it with one click.
Dangerous attachments blocked
Executables and scripts (.exe, .scr, .bat and similar) are refused outright.
Data loss prevention
Gold and Platinum check outgoing mail for card numbers, IBANs and your own patterns.
Brute-force protection
Repeated failed sign-ins are blocked at the firewall across webmail, IMAP and SMTP.
Encryption in transit
TLS for webmail, IMAP, SMTP and server-to-server delivery, with certificates renewed automatically.
Built so your mail reaches the inbox
Good delivery is mostly about not sending what you shouldn't. DiwanMail combines authentication, sending limits and reputation monitoring so receivers trust your domain.
- DKIM signing for every domain, with optional custom selectors
- Hourly MX, SPF, DKIM and DMARC monitoring with alerts
- Sending IP pools by plan, warm-up schedules for new IPs and domains
- Blocklist monitoring with automatic failover to a clean IP (Platinum)
- Feedback-loop complaints from Gmail, Yahoo and Outlook processed automatically
One compromised password shouldn't ruin your domain
Limits and automatic responses that work while you sleep.
Sending limits
Hourly and daily limits per mailbox, domain and organization, plus a cap on recipients per message.
DNS pre-activation lock
A new domain can't send until its MX, SPF and DKIM records are correct (DMARC too on Gold and Platinum).
Anomaly detection
Sudden sending bursts or sign-ins from new places pause the mailbox and alert you.
Rate-spike quarantine
On Platinum, suspicious bursts are held for review instead of delivered.
Spam score monitoring
Mailboxes that keep sending spam-like mail are suspended automatically on paid plans.
Compliance review channel
Platinum customers get a direct line to our compliance team for holds, reviews and investigations.
