EmailServer
Self-Hosted Enterprise Email Infrastructure
Challenge
Businesses want email they control: deliverability, security, and data ownership. Cloud email gives up customization and data sovereignty. Running your own means wiring together MTA configuration, DNS authentication, spam filtering, and security hardening—several moving parts that all have to work, or mail silently fails.
Solution
EmailServer wires proven mail components into one Docker-orchestrated stack. The SMTP layer handles queue management and rate limiting; the IMAP/POP3 service stores and serves mailboxes. Spam filtering learns from what gets flagged, and DKIM/SPF/DMARC signing keeps mail out of spam folders. A Node.js admin API drives domain and user management from code.

- Production-grade SMTP, IMAP, and spam filtering stack
- DKIM/SPF/DMARC authentication built-in
- Roundcube webmail with 2FA support
