In addition to the mechanism to select a mailing-list folder described in See section Guess by mailing-list folders, Mew provides a mechanism to choose a private folder. Since private folders locate under +from, we can say that this mechanism select a folder from the folders under +from. Let's see the following example:
To: pooh@mew.org From: piglet@mew.org
pooh received a message from piglet. If pooh uses this mechanism, +from/piglet will be chosen according to From:. (Folders under +from can be recurse. And you can select the entire address for a folder name instead of the user part.)
The function to provide this feature is `mew-refile-guess-by-from-folder'.
Next, let's consider a care where pooh replied to piglet. Since pooh Cc:ed the message to himself, the message was also delivered to him.
To: piglet@mew.org Cc: pooh@mew.org From: pooh@mew.org
How do you feel if you are pooh? You may want to refile this to +from/pooh. Also, you may want to move this to +from/piglet. So, it can be customized.
If `mew-refile-guess-from-me-is-special' is `t' and if an address in From: is yourself, `mew-refile-guess-by-from-folder' select a folder under +from according to To: and/or Cc:.
