TechMailEmail on Your Own Domains, Fully Under Your Control.
Register, add your domains, verify DNS, spin up mailboxes, and send & receive real email through a clean web UI - all running on infrastructure you own.
A Complete Mail Server, Without the SaaS
From DNS to deliverability, TechMail handles the hard parts of running real email - so you can focus on the mail itself.
Bring your own domains
Add owndomain.com, and TechMail generates your MX, SPF, DKIM and DMARC records. Click verify and we check live DNS over public resolvers.
Unlimited real mailboxes
Create hello@owndomain.com and as many addresses as you need. Each gets its own quota, folders and credentials.
Send & receive real email
A full SMTP/IMAP/POP3 stack - no SaaS email provider in the loop. DKIM-signed outbound, SPF/DKIM-checked inbound.
Self-hosted, fully owned
Your data lives on your server. Nothing routes through a third-party provider for core mail flow. You hold the keys.
A clean webmail UI
A fast three-column inbox with compose, folders, search and message actions - or connect Thunderbird and Apple Mail.
Authenticated by default
DKIM keys are encrypted at rest, passwords are argon2id-hashed, and every outbound message is signed so it lands in the inbox.
From Domain to Inbox in Four Steps
No mail-server sysadmin degree required. TechMail walks you through each step.
Add a domain
Point a domain you control at TechMail. We generate an RSA-2048 DKIM keypair and the exact DNS records to publish.
Verify DNS
Publish the records, click verify, and TechMail checks live DNS. Once they match, your domain flips to Verified.
Create mailboxes
Spin up addresses with standard folders and IMAP/POP3 credentials, ready for the web UI or any mail client.
Send & receive
Outbound mail is DKIM-signed and relayed or delivered straight to recipient MX; inbound is authenticated and stored.
Built for the Inbox, Not the Spam Folder
Google, Yahoo and Apple now require SPF, DKIM and DMARC. TechMail sets all three up for every domain you add.
SPF
Your published SPF record tells receivers which servers may send for your domain. TechMail sets it up so legitimate mail is trusted.
DKIM
Every outbound message is cryptographically signed with your domain's private key, proving it really came from you and wasn't tampered with.
DMARC
DMARC ties SPF and DKIM together and tells receivers what to do with mail that fails - protecting your domain from spoofing.
Loved by Self-Hosters and Small Teams
“We moved three domains off a SaaS provider in an afternoon. DNS verification caught a typo in our SPF record before a single message went out.”
“Finally, mail I actually own. The DKIM signing just works, and our deliverability to Gmail has been rock solid since we switched.”
“The webmail is clean enough for the whole team, and the power users connect Thunderbird over IMAP. Best of both worlds.”
Illustrative testimonials - TechMail is self-hosted software you run yourself.
