Sorry, now I am confused again. This is a mail from Costco to a gmail account. What has this to do with mailcow?
are you assuming mailcow is “gmail.com”?
EnglishEfficiently Setting Up Filters for Bulk Email Forwarding?
esackbauer Of course not.
That’s the current setup: nahidhassen992@gmail.com forwards to: mailservicebrand@gmail.com.
mailservicebrand@gmail.com forwards to my mailcow catch-all address.
That’s why it’s under: “to:”
Now I want to know on how I can set the filter rules as efficient as possible.
Ok, I still do not understand what you want to achieve here. Maybe you can put your use case together so we can better understand why you forward and then forward again. When forwarding is actually bad/old practice.
Forget the forwarding please. That’s mandatory for us, we can’t change.
I’m just asking on how I can apply the filters the best way possible. can I do the Syntax: “mail1” AND “mail2” for example? Or is there any other syntax for this?
Or can I somehow manage the filters differently? For example in a code or with an api?
Do you have a suggestion for this
Thanks already soo much for the help.

Hi.
Are these emails going to a single email account and then you want it forwarded to various people?
Yes -> Using the GUI method above in SOGo will work but will be time consuming. You can instead edit the email addresses sieve filters directly through text and manipulate them that way. However, it’s not possible to do this via mailcows GUI. You will need to find an app that can do this. KMail on KDE has this ability.
You -can- use mailcows GUI to create a pre-filter for emails and do this the same way, though.
If the emails are NOT going to a single email address then you will need to make a global pre-filter to do this.
SimplyCorbett Dear Simply Corbett,
Thanks for your help!
What do you mean by: global pre-filter exactly?
Also do you know an alternative to Kmail on KDE for windows where we can efficiently manage rule filters?
I have seen something like directly modifying the .sieve files inside the mailserver itself.
Is there a good way on how to do it? And does this even make sense?
Like with an external e-mail client or something.
dsn There is an option in the mailcow admin UI called “global pre-filter” which is a text field you can edit.
As mentioned, you can also modify the users server-side sieve filters directly with a mail client such as KMail.
SimplyCorbett Awesome, thanks!
I didn’t know you mean sieve filters with the KMail client. Do you know a KMail alternative that works for windows as well?
I don’t use windows.
dsn Not a desktop client, but Roundcube has a Sieve clinet where you can create rules graphically. You can either install it directly on your Mailcow server, or on any server with a LAMP stack, or in theory even on your desktop computer (preferably in a Linux VM).
