ulaknode — Your email. Your server. Your rules.
ulaknode is a free, self-hosted business email server for Linux, packaged as a single Docker deployment. Run it on your own infrastructure, keep control of your data, and get optional commercial support from itefix.net when you need help with setup, migration, maintenance, or troubleshooting.
Open-source and self-hosted
ulaknode is designed for organisations that want to run their own mail infrastructure without building a complete mail stack from scratch.
- Deploy it on your own VPS, dedicated server, private cloud, or on-premises hardware
- Keep your email data under your control
- Avoid per-user and per-mailbox subscription costs
- Use it freely under a BSD-style license
What’s included
ulaknode bundles a complete production-ready mail stack in a single deployment:
Postfix
SMTP mail transfer for sending and receiving email.
Dovecot
IMAP mailbox access for desktop and mobile clients.
Rspamd
Spam filtering, greylisting, and DKIM/DMARC/ARC support.
ClamAV
Antivirus scanning for incoming mail.
Optional commercial support
ulaknode is free software, but you do not have to operate it alone. itefix.net provides optional commercial support for organisations that want expert help with deployment and ongoing operation.
- Initial installation and onboarding
- Migration from existing email providers or servers
- DNS, SPF, DKIM, and DMARC setup
- Upgrade and maintenance assistance
- Troubleshooting and recovery support
- Spam filtering review and tuning
Who ulaknode is for
A good fit for
- Small and medium-sized businesses
- Teams with privacy or data residency requirements
- Organisations that want to avoid cloud mailbox lock-in
- Companies with in-house IT staff or a trusted service provider
Probably not the best fit if
- You want a fully managed hosted email service
- You do not want to operate a Linux server at all
- You are looking for a consumer-style mailbox platform instead of infrastructure control
Free software, commercial support available
ulaknode is available under a permissive BSD-style license, so you can deploy and use it freely on your own infrastructure. There are no per-user, per-mailbox, or per-domain license fees.
For organisations that want expert help, commercial support is available for purchase from itefix.net. Support plans start at $549 per year, with discounts for two-year and three-year terms, as well as volume pricing for multiple installations.
Commercial support can include deployment guidance, migration help, upgrades, troubleshooting, and deliverability tuning.
Run your own mail server — with support available if you need it.
Use ulaknode freely on your own infrastructure and keep full control over your email environment. When you need expert help, itefix.net is ready to assist.
