v0.1.1 · MailOps live
Email you host,
not email that hosts you.
Oasis builds Zimbra FOSS from source and deploys it through Docker: email, calendars, contacts and collaboration on your own infrastructure. One command takes a bare Linux host to a working mail platform — with migration presets, health monitoring and compliance reporting.
$ git clone https://github.com/innotelinc/oasis.git && cd oasis && cp .env.example .env && ./build.sh
Mail, calendars and collaboration — self-hosted.
A production mail platform built from upstream source, deployable on any Linux host with one command.
Zimbra FOSS from source
The full Zimbra build — mail, calendar and contacts servers — reproduced and containerized.
One-command deploy
`./build.sh` takes a bare host to a working mail platform; `setup-oasis.sh` handles lifecycle.
Mail security
Posture checks with exit codes for cron, `--json` output and dated Markdown compliance reports.
Migration presets
imapsync-based migration from Exchange, Google Workspace and Zimbra with per-provider presets.
Edge + wildcard TLS
app/api/auth/mail/files/admin hostnames provisioned in NPM with a wildcard Let's Encrypt cert.
Health monitoring
`oasis-health.sh` checks the whole mail posture — SPF/DKIM/DMARC and service health.
