[Users] Applying Filtering for Specific Folders Only

[klt at fsfe.org]

Hello,

can I restrain filtering to a specific folder?

I use the Nachverarbeitungsregeln to get new mails moved automatically
from INBOX to varying intermediate folders AFTER skimming or reading
them.

However some mails I move directly from INBOX to Trash, or put them to
some archive folder when no action of mine is needed.

But when I open the Trash/archive, its content is moved to the
intermediate folders by the Nachverarbeitungsregeln.

How can I set filters to be applied to messages in INBOX only?

Thanks for your help,
Klaus
