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
Mailman 3
- Focused on discussion lists, not marketing newsletters
- No campaign analytics or click tracking by design
- Setup of the three-component stack (core, Postorius, Hyperkitty) is non-trivial
Bottom line
Choose Mailman 3 if you want the lower-effort setup; 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.
