Hi again Ton, that is of course not possible.
Thank you,
Paul.
Which makes your suggestion not very usefull. 
Anyway, keep up the good work and certainly hope that you put this feature high on the to-do list 
Simple logic concludes that doesn’t work. I have hundreds of people whose mail I route to a business folder via one inbound email account. I’m not going to create hundreds of rules.
