Hello, tell me pls how user can use filter rules if NOT. for example if email received NOT from *

@Constin This can be done with kopano-rules

The following WebApp tickets apply to this:

Follow those to receive status updates.

there is no rule “IS NOT” in kopano rules


There is you need to use the exceptions parameter for that.

python --user user1 --create firstrule  --exceptions "" --actions ""

These exceptions are not visible in WebApp (yet) but they are working
