Hello mailcow folks 🐄,

"After update is before update", so always update your cows please, no matter if there is a summary on mailcow.email. 🙂

Before we start I want to remind you of an important change that’s about to happen tomorrow:

mailcow, including me, will be part of "The Infrastructure Company GmbH". No, mailcow will not be discontinued. No, I will not stop to work on mailcow.
You will probably not notice the change at all. Hopefully we will be able to finally implement more features soon as there will be more time to work on mailcow.

We still rely heavily on your support (support contacts, SAL etc.) to continue mailcow as it is. As long as we don’t have a commercial plan or "paid version" of mailcow, that’s the only way for us to finance the work on mailcow.

What’s new?

Many bugs were fixed and existing features were cleaned up.

What’s next?

Disclaimers/signatures with variables to use in a pre-defined template per domain and mailbox. 🙂

Thanks to Andreas we recently discovered something great…


…and its name is Delta Chat!

Before you move away: No, it is not yet another messenger. Or is it?

It is something in between. Delta Chat uses email to transport its messages. Your email server.

  • Delta Chat does work with "autoconfig". Enter your mailcow email address and password and your are ready!
  • Delta Chat automatically encrypts messages using Autocrypt – no setup needed!
  • mailcow comes with a sieve prefilter to move all chats to the preconfigured DeltaChat folder (since commit 3dece1)
  • Communicate with any email recipient, every client uses their own email server.

So what do I need?

  • The app, get it here
  • A mailcow or basically any other email account

…and 2021 is just around the corner! 🎆

It’s an understatement to say that 2020 was a strange year and, for sure, challenging for many of us in so many different aspects. I hope you’re fine and enjoyed your recent days with your loved ones.

If you don’t want to read further:
We wish you a very happy New Year! 🎉

😻 To focus on the positive things from a mailcow point-of-view, there were indeed quite some highlights in 2020:

  • Early this year external open relay checks were implemented for SAL users (supporting the development) was introduced. (see news)
  • In February 2020 our own fuzzy storage was launched, improving spam detection for all mailcow users and allowing to contribute spam emails. (see news)
  • In March 2020 we’ve started a official community forum with great success.
  • In July 2020 our sponsored improvements for the new identity management to SOGo made it into the public release: check it out!
  • Access to IMAP, POP3 and SMTP can now be controlled on a per-user level, also last logins for each service can be seen in the webinterface. (see news)
  • FIDO2/WebAuthn support was added to mailcow in November 2020. (see news)
  • You can easily integrate your mailpiler instance – open-source-based email archiving solution – with mailcow: see docs.
  • Also good to know: Deprecated TLS versions TLSv1.0 and TLSv1.1 were disabled, mailcow can now speak Romanian and Chinese.

📝 Two more things I want to note…

✍️ First… Telegram.
In July 2019 we’ve started with a Telegram group for mailcow, where – to date – joined over 920 individual, awesome people! The positive feedback, how people help each other and the new friendships found this way… It’s unbelievable!

Thanks for being part of this community. This is what makes our community that great: It’s made up by awesome people – like YOU.

❤️ Second… Contributors.
THANKS for every contribution – and it doesn’t matter if it’s helping other people, sharing the mooo, contributing code or simply silently using mailcow somewhere.

Also there’s something what we might often take for granted: mailcow consists out of so many different components, where people invest their valuable time in and provide it for free to everyone.

Thanks for all the good work from people behind Postfix, Dovecot, rspamd, Docker, SOGo, unbound, clamav, LetsEncrypt and so many more. Mailcow wouldn’t exist without you.

That being said…
Thanks for all, stay healthy and Happy New Year. 😘

Patrik and Andre

Welcome FIDO2 to mailcow!

We recently pushed a change to integrate FIDO2/WebAuthn support for administrators and domain administrators to mailcow.

mailcow FIDO2

Please see our docs for further information.

We are working to be listed on Works with Yubi in the near feature.

Quick note: A single SMTP recipient "postmaster@…" is now whitelisted by default.

Previously we included a settings map template to manually enable this behavior. This template is now dropped. It does not hurt to keep the old settings map, it will just never be applied.

Same for outbound: No matter the authentication, a SMTP FROM postmaster@… will be score -2500.00. No prefilter is applied to keep signatures.

-2500.0 will also skip ClamAV-positives, please keep that in mind, do not forward viruses.


It’s been a long time since I wrote other posts than updates.

My daughter was born almost a year ago. My life changed quite a lot, I still don’t feel like I reached my goals and that there is going to be more fantastic changes to come. Thank you guys for contributing to mailcow and enlighten my day – every day.

InterServer started contributing fuzzy hashes to mailcow. If you have a spam trap by hand and feel like sharing, please contact me. Thank you, InterServer; thank you, John.

What could be next?

  • I will try to add hooks to mailcow UI. I want to implement individual hooks that can run after adding a domain, mailbox or other elements. The "push" hook like we already have with Pushover will be moved to that logic. Users will be able to control push hooks, domain admins as well as admins will be able to add hooks to other logics like adding a mailbox, domain or alias etc.

  • I will add a HTTP map to resolve aliases to their final recipients. This way we can finally fix the tag handling for alias recipients and make black/whitelistings more granular.

Please join us on Telegram, if you have ideas to share or just want to hang out. 🙂


By the way: We update the code on a regular basis, you do not need to wait until we post these overviews. 🙂

Notable changes for all cows

  • Please contact me, if you want to share your spam with mailcow => info@servercow.de
  • We sponsored a better identity management in SOGo
  • .doc and .xls are now only rejected when they contain macros
  • mailcow speaks Chinese! Thanks to @EHfive!
  • You can now limit access to IMAP, POP3 and SMTP per user
  • Rspamd 2.6 with new neural logic
  • A vmail-index-vol-1 volume was created. The mail index will be recreated on the fly when accessing a mailbox. You can move this volume to fast disk and keep vmail-vol-1 on slower/spinning disks.
  • Show last SMTP login
  • We do now fully encrypt connections to the fuzzy storage
  • iso/img are now bad attachments
  • Disable extension cloaking detection (i.e. "doc.exe") due to false positives and other checks catching these bad extensions
  • rspamd-stats are available via mailcow API (/api/v1/get/logs/rspamd-stats)
  • Watchdog is enabled by default now when installing mailcow
  • New ACL to allow or disallow a domain administrator to change the domain description
  • Update MariaDB to 10.4

There are many more useful changes, please see the list below. I could not decide between important and less important this time. Many changes are quite useful or simply important bug fixes. So: update time!

A BIG THANK YOU to all supporters! Thank you so much for keeping mailcow alive. 🙂
Another BIG THANK YOU goes out to all contributors!

A lot of people asked for a way to bulk create mailcow accounts via CSV file. Appcoders delivered a solution for this and other mailcow related tasks.

Big thanks to appcoders!
