NethServer Version: 7.5.1804 (final) Module: Email Hello, just the next newbie question after the first was answered so quick :smile: Is it possible to filter emails not at user level but at server level? Let’s say one special account receives emails from one special customer but I want to for…

Think I’ve got it, I try to tell what I did until now Nethserver uses the e-smith or SEM-Server template system so I looked in their documentation. The file, where the server-wide filter settings should be defined: /var/lib/nethserver/sieve-scripts/before.sieve This file is created from the templ…

Hi Uwe, Nethserver uses Sieve for filtering. You may setup rules with roundcube, thunderbird or other clients . [image] hinzberlin: I come from hmailserver Me too. I still use it in some Windows environments.

Hello Markus, thank you, you’re very active here :+1: I’m afraid you misunderstood my question: filters I create in roundcube/Thunderbird… are for that special user, they get saved in /var/lib/nethserver/vmail/USERNAME@example.com/.dovecot.sieve -> sieve/sogo.sieve (correct me if I’m wrong) I w…

Sieve works for whole domains too: Sieve Email Filtering | Tiger Technologies Support You can use Sieve mail filters to control how mail is delivered. There are sieve scripts in /var/lib/nethserver/sieve-scripts/. Don’t edit them directly, they are template…

Thanks for this contribution! [image] hinzberlin: But you must not include require [“fileinto”, “mailbox”, “copy”]; in your own filter file because it would apprear twice in before.sieve and you would see an error in /var/log/mailog I could not reproduce the sieve error in /var/log/maillog, …

Hello Markus, when you use the default 10junkmail AND your own 20mailfilters and your 20mailfilters has the line require [“fileinto”, “mailbox”, “copy”]; as 10junkmail has too Then the generated /var/lib/nethserver/sieve-scripts/before.sieve will contain two of these lines, one in the 10junkmail …

I wonder if we could workaround the require problem with include scripts: https://wiki2.dovecot.org/Pigeonhole/Sieve/Examples#Include_scripts This way we still have to change the first require to make the include scripts work but then we may use separate scripts with our own require commands. If …

What about removing the start of before.sieve and the require line from 10junkmail into a new file 05requires. In my theory 05requires is always executed, 10junkmail only if the setting “send spam to Junk folder” is active and after that comes our 20mailfilter and every other file. If you need a n…

That’s possible too, but the goal is not to change original templates and not to override templates directly with template-customs with same name because if future system updates change templates it will have no effect. I think best way for now is to disable Junk folder with config setprop dovecot…

I just saw that now there is a file /etc/e-smith/templates/var/lib/nethserver/sieve-scripts/before.sieve/10sieveExtensions that only includes all the needed sieve extensions and comes first when before.sieve is generated. So you may copy that file into your custom templates folder and insert all …
