What is your setting for what to select after moving a message or opening a mailbox? I long missed an option to 'select nothing' (until I patched it into KMail 4.1x myself, *partly*). If somehow your filter generates a selection event that would explain why the message is marked read.

FWIW, my setting for "mark as read" is "after 2 seconds" which usually gives me enough time to hit the cursor keys to move the selection away from a message I don't want to open when it gets  selected automatically. Sometimes akonadi takes so much time, however, that those 2 seconds aren't enough >:-(

I can't help you with the filtering though. I do mine on the server (because I can, and because that means it also works when I read my mail via my phone or Thunderbird).
