Message filter log seems empty
It's not that message filtering isn't working, most of my filters are working fine. And the one that isn't is probably my fault.
So I've had the filtering log enabled on two accounts for a couple of weeks now. Many messages have been processed through filters. But when I look at the filter log, all I see is two folders, one empty and one containing the headers for a blank html file. I see nothing about filtering.
Both accounts are set up for maildir. Does the filter log work on maildir? Or must I do something other than clicking on the Filter Log button in the Message Filters dialog?
