(I did try searching for a bit before posting)
I have a user that uses subfolders extensively. My spam filter is trained pretty well, however there are still the occasional issues with false positives. This user has been in the habit of moving these false positives straight to a subfolder instead of to the inbox (she uses an IMAP client, and not the web interface).
Here is my question: when ham is moved from the junk folder to a subfolder, is a copy still sent to the ham e-mail address? Or does that only happen if it is moved to the inbox first and then filed away into a subfolder?
