mailcow mailserver suite
News and notes
Just merged new code and pushed new images.
Watchdog has no docs available yet, I am working on it!
Update: Thanks to Antoine Sirinelli we now have French language support!
We will merge dev to master soon. Checkout the new screenshots for new features! Ratelimit per domain and user, customisations and much more. A new watchdog will be introduced to check the health of your cow and restart unhealthy containers automatically (still a WIP). 😊
We just merged new code! Please join our IRC channel if you have any questions.
First of all I would like to thank you for your donations! I very much appreciate your help and cannot thank you enough for this. Thanks, thanks and thanks again. 😊
Some interesting and useful features were changed or added to mailcow over the past weeks.
A very interesting change was made to the Fail2ban-like system, that now reads logs from a Redis channel to not be dependent on Dockers Json logging driver anymore.
Another feature was introduced with an update script you will find in your mailcow root directory. It will update itself before executing any code. Most conflicts will be auto-resolved (in favor for the mailcow repository).
Other features include the ability to import private keys for DKIM and ARC (yes, we have ARC support!), SKIP_CLAMD to not run ClamAV and save some (a lot) memory - which by the way will be auto-detected as down by Rspamd -, updated Dovecot + Pigeonhole code, SKIP_FAIL2BAN option, a ACME-client to auto-request Let's Encrypt CA signed certificates, settings for Fail2ban in the Web UI (whitelist, ban time, retry time frame etc.) and more...
I hope we can switch to a better mailcow.email website soon, which should then parse the commits as some kind of changelog. Let's also look forward to implement SOGo 3.2.10, which will introduce EAS v16 support!
Please ignore a previous announcement to use a DNSSEC enabled local DNS server. We decided to replace Bind9 by Unbound instead of removing it from mailcow: dockerized.
There were slight changes to the reverse proxy configuration. So if you use such a setup in front of mailcow: dockerized, you should update your configuration after pulling the latest changes from Git.
Until changes and improvements made to mailcow: dockerized are merged to the non-dockerized mailcow, it is recommended to use mailcow: dockerized.
Please excuse the huge delay, my time is very limited and development is primarily done in my free time.
11 containers and 4 volumes combine to a Docker conform mailcow installation.
mailcow: dockerized will be a rolling release in the master branch @ GitHub. There will be a dev branch soon, which should not be used.

A fresh installation is recommended!
- WebUI per mailbox: Enforce in- and outbound TLS
- ! Works best with Postfix >=3.0 (*uses smtp_dsn_filter to turn temp. TLS errors to perm. errors to notify client instantly)
- WebUI per mailbox: Set black- and whitelist records for spam filter
- WebUI: Drag and drop Postfix restrictions
- Switched WebUI to PDO database interface
- Added some options to /var/www/mail/inc/vars.inc.php (please use
vars.local.inc.phpto overwrite settings)
- Multi-language Web UI (English, Portuguese and German)
- Fixed errors in Web UI
- Removed backup from Web UI and added "mailcow-backup-mail" script
- (Hopefully) RFC compliant email addresses
- Z-Push removed - choose between SOGo (ActiveSync + DAV) and Roundcube
- Better Sender ACL (find it at "edit mailbox")
- Fail2ban was removed and should be setup according to your own setup
- letsencrypt.sh/dehydrated was added to provide a signed certificate (optional)
Thanks to Brad we now have a Discourse instance online for you to find help installing/configuring mailcow!
We can finally stop using Github as our forum and keep using it for real issues and bugs. :-)Visit forum
