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
Sympa
- Perl stack and complex config make setup challenging
- No modern marketing analytics or A/B testing
- Web UI is functional but not modern by current standards
Bottom line
Both are a similar lift to self-host; choose docker-mailserver for the larger community and ecosystem. docker-mailserver has seen more recent development. Open each guide below for deploy steps and the full feature gap.
