Your inbox now lives
on your own server.
A production-ready mail server runs inside your ODAC node. Send and receive from your own domain over SMTP and IMAP, with DKIM, SPF and DMARC configured for you. No SendGrid, no Mailgun, no Google Workspace.
Deliverability, handled
Built to land
in the inbox.
Self-hosted mail has a reputation for landing in spam. ODAC configures the hard parts for you, so every message you send is authenticated the way the big providers expect.
- Every message is signed with a 2048-bit DKIM key, automatically.
- SPF is generated with your server's real IPv4 and IPv6 addresses.
- A strict DMARC policy is published from day one.
- The sending IP is matched to its PTR record, with IPv6-first delivery.
Send and receive
Not a send API.
A real inbox.
ODAC ships a full SMTP and IMAP4rev1 server in a single binary, so your accounts can actually receive mail, not just send it. INBOX, Drafts, Sent, Junk and Trash are created on first login, and it speaks the extensions modern clients expect.
STARTTLS and implicit TLS, minimum TLS 1.2. Login is refused until the connection is encrypted, so your password never crosses the wire in the clear. IDLE, UIDPLUS, NAMESPACE and SPECIAL-USE keep Apple Mail, Outlook and Thunderbird happy.
Hardened by default
A fortress around
your mail.
A mail server is a target the moment it comes online. ODAC assumes that and layers its defenses so a single bad actor cannot brute-force, relay through, or impersonate its way in.
Built for real workloads
A real mail server.
None of the ops.
High-performance Go
A connection-per-goroutine core with auto-raised file-descriptor limits, outbound connection pooling and a one-hour MX cache. Scales toward roughly 10,000 accounts on a single node.
Zero-downtime updates
Port binding retries automatically until the old instance lets go, so the mail service stays reachable through ODAC's blue-green updates. Mail is never dropped mid-deploy.
Multi-domain, per-domain SSL
Host mail for many domains on one node. Each domain is served its own TLS certificate over SNI, wired into ODAC's automatic SSL issuance and renewal. Embedded SQLite, no external database.
Your first mailbox, in one command.
