Hooks are a feature of mutt that allow for certain dynamic / automatic
behavior. NOTE: commands / settings are NOT
restored after execution / processing of a hook. You have to provide a
"default" match, that will catch everything that doesn't match your
specific case. However, do not provide a resetting "default" match for
hooks which do not run a command (and change a setting).
mbox-hook foldername-regexp foldername
You can specify more than one "move-target" for read messages when you
have more than one different "inbox" folders defined by mailbox-cmd.
This is useful when you use "procmail" to sort incoming email
automatically into separate folders and need for each their own "read"
folder-hook foldername-regexp command
Every folder-hook that matches is executed.
The order matters: the latter overwrites the former.
You need "." as the default to initialize for all cases that are not
explicitly set in the following hooks.
Applies only when you actually open the folder, just accessing/
listing it in the folder-browser is not enough.
