Configurable rules by folder?

Jim

Several mail providers offer the ability to set rules on a folder by folder basis. For example, with my current provider, I have a folder “Promotions and Marketing” and I purge messages older than 14 days from that folder. Is this something I can do with Mailcow/Sogo? I looked through the documentation and didn’t see anything.

Thanks,
Jim

Then you didn’t see this 🙂

MAGIC I did see that, and that’s a solution that will work fine for some global rules. What I’m after, though, is a way for end users (and there will be a few) to configure and implement rules on their own. A user shouldn’t have to login to the host and setup a cron job to manage a mail folder. Know what I mean?

MAGIC

Jim Indeed yes.
Maybe @diekuh can implement this somewhere in the UI

A user can also create a filter in their client.

Jim

diekuh I agree - they can, and modern clients like Outlook, Thunderbird, and a host of others make this pretty easy. However, when the client is Sogo, for example, it seems as though this is currently not an option.

Maybe my question is more appropriate for the Sogo community than for this one.

If you have different devices and clients there is a need to have “server” based rules. Other wise the rules are only executed if the client with these rules is running. This is often not the cases, e.g. if you configure the rules on your client on the laptop and also use a mail client on your mobile phone.
As far as I know this functionality is available in Outlook in combination with :Exchange, but also in Kolab configurable in Roundcube.
In Kolab this is done by writing sieve rules based on the configuration done in the UI.
As far as I know mailcow uses dovecot with sieve, thus it should be possible to implement rules in the UI. This would be great 🎉

You can do this with Thunderbird:
https://addons.thunderbird.net/en-US/thunderbird/addon/sieve/
Unfortunately its not working with newer Thunderbird versions, but there seems a nightly build which should work:
thsmi/sieve893
And a working release is just around the corner.

@esackbauer Thank you for the hint.

It seems not very smart for me to install Thunderbird only for managing sieve rules for my account on the mailcow server. The smart place would be the mailcow UI.

This is how it looks like in roundcube in Kolab (the corresponding UI to the mailcow UI and SOgo):

The generated sieve rule is /var/lib/imap/sieve/domain/w/.../l/.../Kolab.script

require ["fileinto"];
# EDITOR Roundcube (Managesieve)
# EDITOR_VERSION 9.3
# rule:[lists.kolab.org]
if anyof (header :contains "to" "lists.kolab.org", header :contains "cc" "lists.kolab.org")
{
	fileinto "news/kolab";
}

I am currently migrating from Kolab to mailcow and we are really missing this possibility.

No it would be SOGo, as SOGo is already using Sieve for its rules.
So the best bet would be to write a feature request for SOGo on their bugtracker.

Perhaps I misinterpreted the configurations done in the dovecot entry script, aren’t there a series of sieve configurations?

I just saw that logo already has this feature.
