Email Filtering Rules (Sieve)

Mville

Hello MailCow ComMOOnity!

Loving all the bovine meme’s etc… This is truly a great email system/service, especially love the EAS support on the back end. Thank you to all that contribute to this project.

So, I’m new here, I’ve migrated from Grommunio -> MailCow (dockerized) using ‘imapsync’ (another great piece of software).

So far, everything is working well, but I have a question regarding email filtering.

When using Grommunio, I can create an email filtering rule in Outlook, these rules would then show up in other Outlook instances I connect using my account. And would work as expected.

The (minor) issue I’m hitting right now: on the windows device running Outlook, the rule(s) appear only there in that instance. When I log into my other Windows 11 instances, the rules list is empty?

In Grommunio, this was not the case, an email rule would be seen in every instance of Outlook I connected to Grommunio, (my own account of course).

To test this, I created a few email rules in the SOGo WebMail interface, but still they don’t show up in Outlook. Conversely, when I create a rule in Outlook, only the Outlook instance where I created the rule would have it. The Webmail and other Outlook instances would be empty.

Is this ‘normal’, or am I out to lunch on email filtering? 🙂

Any pointer would be most appreciated.

Edit: I only use EAS protocol, I do not use IMAP services. As with Grommunio, only EAS service was used, not IMAP.

This is normal. With mailcow you need to define rules only within SOGo, they are not visible in Outlook.
However those rules will then be active, no matter what client you are using.

Okay, then that’s my way forward with email filtering.

Thank you!

I’ve got another question regarding email filtering (sieve rules).

I have a few users to migrate from Grommunio to MailCow.

As for sieve email rules, I was able to export the users rules from Grommunio.

I tried to add a simple rule using the same syntax I see in sogo.sieve file, but the changes are never picked up by dovecot container/service. Even rebooting, the changes never show up in the Webmail.

I edited this file to try to add just one new sieve rule:
/var/lib/docker/volumes/mailcowdockerized_vmail-vol-1/_data/example.org/john/sieve/sogo.sieve

First, is it possible to do what I’m attempting?

If yes, what is the method to get dovecot to pick up the changes in the sogo.sieve file?

Thank you!
