Full-stack business email on AWS EC2 — Postfix, Dovecot, SOGo, Rspamd, ClamAV — deployed via Docker Compose.
AWS EC2 instance with EBS storage. Docker Compose orchestrates Postfix (SMTP), Dovecot (IMAP/POP3), SOGo (webmail, calendar, contacts), Rspamd (spam filtering with Bayesian learning), ClamAV (antivirus), Redis, and MariaDB. Nginx reverse proxy with Let’s Encrypt SSL auto-renewal. Daily EBS snapshots with 30-day retention.
One terraform apply provisions the EC2 instance, security groups, EBS volumes, and Route53 DNS. Docker Compose starts all services. SPF, DKIM, DMARC configured for deliverability. Health monitoring dashboards via EC2 agent. IP warm-up guidance included.
Google Workspace costs $18/user/month. A 50-person company pays $10,800/year — and costs scale with every hire. Self-hosting email is technically demanding: Postfix, Dovecot, spam filtering, antivirus, SSL, backups. Most PYMEs cannot manage this themselves.
This module solves the self-hosting problem. One command deploys a complete Mailcow stack.
