[RCU] Filter-Rules

Hello,

in the last few days the german mail provider GMX reduced massively their filter-rules. I've used for over ten years the rule X-BeenThere to move emails from/via mailinglists to a subfolder. This header-filtering is now disabled! Now my incoming mail folder looks very disorganized. I lose track!

Is there a possible way to let roundcube do these filtering/moving automatically for me?

Or is there an other german recommendable mail provider which offers this functionality? I am willing to pay for this service. Currently I pay 3 Euro/month to GMX (ProMail)

Best regards from germany
