emailwiz
Bash-based installer that deploys a secure Debian/Ubuntu mail server stack.
emailwiz is a Bash-based installer for Debian/Ubuntu that automatically deploys a complete mail server stack comprising Postfix, Dovecot, SpamAssassin, and OpenDKIM, with TLS via Certbot. It configures PAM-based logins and security features like fail2ban.
Key Features
- Automates installation and configuration of Postfix, Dovecot, SpamAssassin, OpenDKIM, and Certbot TLS
- Links Postfix and Dovecot securely with native PAM log-ins
- Includes fail2ban for server security
- Provides guidance and finishing steps for DNS records (MX, SPF, DMARC, DKIM)
- Offers an isolated/self-signed certificate option for private environments
- Targets Debian/Ubuntu as the operating system
Use Cases
- Deploy a standalone mail server for a small business or home lab on Debian/Ubuntu
- Set up DKIM, SPF, DMARC and TLS to improve email deliverability
- Rapid provisioning of a mail server with minimal manual configuration
Limitations and Considerations
- No graphical webmail interface is installed by default; a mail client is expected
- DNS configuration is required (MX, SPF, DMARC, DKIM) for proper deliverability
- An isolated/self-signed certificate mode exists but will not work for public mail delivery
- The project emphasizes UNIX user accounts (no SQL database)
Conclusion
emailwiz provides an automated, script-driven path to a secure, mail-server setup on Debian/Ubuntu, reducing manual configuration and ensuring standard mail components and DKIM/TLS are in place. It is linked from the author’s site and maintained as a Bash script intended for self-hosted deployments. (github.com)
