Thunderbirds filter function allows me to create such an animal, but it only works on the account where it was created, which forces me to run the filter manually on about 50 % of the traffic. To get things the way I want them, I will be forced to create the same filters in all of my seven accounts, which makes it impossible to keep the intricate rules up-to-date. Reproducible: Always Expected Results: A filter should be allowed to work on all accounts and folders, or - maybe practical for others than me - on chosen accounts and folders.
