docker-mailserver vs poste.io
Same container, with an interface
docker-mailserver and poste.io agree on the architecture. We disagree about who should be able to add a mailbox.
- 10M+ Docker pulls
- 2014 shipping since
- 1 container to upgrade
Where they differ
| poste.io | docker-mailserver | |
|---|---|---|
| Administration | Web UI anyone can be handed | Config files and CLI |
| Webmail | Roundcube included | Bring your own |
| REST API | Included | — |
| Delegation | Domain admins and mailbox owners | Whoever has shell access |
The same on both: One container, Upgrade by replacing the image, Rspamd spam filtering, Dovecot IMAP/POP3, ClamAV antivirus, Unlimited domains and mailboxes.
Being fair about it
docker-mailserver is a great project and shares our core idea: the whole mail server in one container. If your mail server belongs in your configuration management and nobody else needs to touch it, docker-mailserver is an excellent choice.
If somebody other than you has to add a mailbox, poste.io may be a better fit.
What you get either way
- Tested as one unit SMTP, IMAP, spam filtering, antivirus, webmail and administration are exercised together against real servers before an image ships. A version bump in one part cannot quietly break another.
- Backward compatible Your data and your configuration survive upgrades. We have not asked anyone to reinstall since 2014.
- No babysitting Upgrading is always the same thing: replace the container. No procedure, no migration script, seconds of downtime. We can do it for you.
- Monitoring included The server watches itself. If you want somebody else to be the one who notices, we can watch it from the outside and step in.
- Custom work is possible The whole thing is ours, so we are not waiting for an upstream project to accept a feature. Tell us what you need.
- Not a weekend project Shipping since 2014, 10M+ Docker pulls, and paying customers who have been with us for years.
