Where each falls short
The honest trade-offs — what you give up with each, versus the proprietary tools they replace.
docker-mailserver
- No admin web UI — all config is via files and the CLI
- No bundled webmail or groupware (calendar/contacts)
- Deliverability, DNS, and TLS setup are entirely your responsibility
- Not a newsletter/marketing tool — mailboxes only
SimpleLogin
- Self-hosted instance requires managing its own MX record and email reputation
- No bulk sending or newsletter features; purely an alias/forwarding tool
- Mobile apps connect to SimpleLogin's cloud by default; redirecting to self-hosted requires manual app configuration
- Spam filtering is inherited from the destination mailbox, not provided independently
Bottom line
Choose SimpleLogin if you want the lower-effort setup; choose docker-mailserver for the larger community and ecosystem. SimpleLogin has seen more recent development. Open each guide below for deploy steps and the full feature gap.
