[MlMt] Automated filing by tags

[Paul Atlan]

I want to use tags as a way to track some of my mail and create nice 
smart folders, but using IMAP folder is a nice way to manage my mail "on 
the go" with my iPhone.
I have a folder on my mail server called "file cabinet" with subfolders 
by topics, which map to tags (same names)
I want to :
* if I save a message to the folder, tag it with the name of the folder
* if I tag a message, save it to the corresponding folder (instead of 
archiving it)

So for now, I need to map carefully each tag to a folder and vice versa, 
and set up the corresponding rules ... it's a pain.

Is there a way to specify a generic rule (if the tag is XXX, file in 
folder file cabinet/XXX) ?
