Business email on your own domain, fast websites with automatic HTTPS, and DNS — all on Zambian infrastructure, with your data and keys kept yours. Designed to support your obligations under Zambia's Data Protection Act 2021 and Cyber Security Act 2025.
Any business or individual can bring their own domain — no mail server to install, no MX migration headaches. Sign up and we provision everything for you.
Enter your domain and an admin email. We instantly create your workspace, a catch-all mailbox, and your DKIM key.
We show your exact MX/SPF/DKIM/DMARC records with copy buttons and step-by-step guides for GoDaddy, Namecheap, Hostinger & more. The MX record is the one that switches your domain on.
Publish the records and re-check — the moment your MX points here, your domain verifies and switches on automatically. Send and read from webmail, the OMail app, or the REST API.
Browser, desktop mail clients, and API calls read and write the same Postgres mailbox — flag a message in Apple Mail and it's flagged in webmail instantly.
An SMTP daemon accepts internet mail for any registered domain, with catch-all routing and open-relay protection.
Send straight from your domain with per-domain DKIM signing, or relay through your own provider — your choice.
Reply, forward, drafts, a rich-text composer with Cc/Bcc and attachments, bulk actions, custom folders, dark mode and keyboard shortcuts — on desktop and mobile.
A hand-rolled IMAP4rev1 server lets Thunderbird, Apple Mail, and mobile read the same Postgres mailbox.
Every send gets an undo window; pick a future delivery time and a background worker relays it when due.
Replies fold into conversations, and full-text search with operators — from:, subject:, has:attachment, before:/after: — returns ranked results instantly.
Per-mailbox rules match from/to/subject/body and move, flag, mark-read, or trash on delivery — applied by the MTA itself.
Reusable subject/body templates and per-mailbox signatures, applied right in compose.
Know when a message is opened, a link is clicked, or an attachment is downloaded — with a per-mailbox dashboard and your own tracking domain.
One tap distils a long message or thread into the key points — right in the reader, no copy-paste.
Pair a phone in seconds — scan the code from webmail to sign into the OMail app, no password typing.
A loop-safe vacation auto-reply while you're away, and auto-forwarding to copy incoming mail wherever you need it.
Self-host it (air-gapped if you need) or let us host it — you keep the data and keys, with an audit log of every admin action and full customisation.
Bring your own domain — you only pay as your team and volume grow.
Perfect for a small team getting professional email on its domain.
For growing organizations with multiple domains and teams.
Unlimited scale with a dedicated sending identity and SLA.
Run your whole online presence in one place — register a domain, host its DNS, get email, and put up a website, all under one account.
Self-hosted mail you own — webmail, IMAP & API.
Authoritative nameservers (ns1/ns2.ontech.co.zm) and a full records UI — manage it in your dashboard.
Search, register, transfer and renew domains in-platform.
Fast websites on our Zambian servers with automatic HTTPS — email and DNS built in.
Run it on your own infrastructure (air-gapped if you need to) or hosted — the mail and the keys never leave your control. Every admin action is recorded in an audit log, designed to support your obligations under Zambia's Data Protection Act 2021 and Cyber Security Act 2025.
Everything you need to know about owning your email.
Yes. The whole stack runs on your own hardware — even with no internet egress. You hold the mailboxes, the data, and the DKIM keys; nothing depends on us once it's deployed.
Completely. Mailboxes, attachments and keys live on your infrastructure, isolated per organisation, and every admin or provisioning action is written to an audit log you can inspect.
Data residency on your own infrastructure, an audit trail, two-factor authentication and encryption in transit are the technical building blocks that support compliance with Zambia's Data Protection Act 2021 and Cyber Security Act 2025. Compliance itself depends on your policies and processes; see data sovereignty for what the platform does and does not cover.
Yes. Read with IMAP (mail.ontech.co.zm, port 993, SSL/TLS) and send with authenticated SMTP submission on port 465 (SSL/TLS) or 587 (STARTTLS), using your full address and mailbox password. Autoconfig and autodiscover are published, so most clients set themselves up. See the IMAP and SMTP guides.
Sign up with your domain, publish the MX/SPF/DKIM/DMARC records we generate (with copy-paste guides for popular registrars), and you're live. Your current mail isn't touched until you switch the MX.
We ship a tunnel-based cloud relay so you can still receive internet mail without opening any inbound port — your server dials out and the relay hands mail back over the tunnel.
Your full inbox on the go — read, send, search, attachments and instant QR sign-in. Now on iPhone and Android.
Any business or individual — bring your domain, add a few DNS records, and once your MX points here you're live on the web and the OMail app.
