iRedMail vs poste.io
A container, not an installer
iRedMail installs a mail server onto your machine. poste.io hands you one the machine knows nothing about.
- 10M+ Docker pulls
- 2014 shipping since
- 1 container to upgrade
Where they differ
| poste.io | iRedMail | |
|---|---|---|
| Deployment | One container on any Docker host | Installer that configures the host |
| Upgrade | Replace one image | Upgrade procedure on the host, per release |
| Domain admins, REST API, log viewer | In every edition | Paid edition |
| Released as | One unit, tested end to end | Component by component, on your distribution |
The same on both: Dovecot IMAP/POP3, Roundcube webmail, SPF, DKIM, DMARC, Web administration, Unlimited domains and mailboxes.
Being fair about it
iRedMail is a great project and has been around even longer than we have. If you want the mail server to be part of the machine, packages and all, iRedMail does that deliberately.
If you would rather move it between hosts and upgrade it by replacing one image, 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.
