@chapter Dynamic folders
In @ref{Folders} we gave an example of setting the standard folders:
@lisp
(setq
mu4e-sent-folder "/sent" ;; where do I keep sent mail?
mu4e-drafts-folder "/drafts" ;; where do I keep half-written mail?
mu4e-trash-folder "/trash" ;; where do I move deleted mail?
mu4e-refile-folder "/archive") ;; where do I move message after completion?

mu4e-drafts-folder "/drafts" ;; unfinished messages
mu4e-trash-folder "/trash" ;; trashed messages
mu4e-refile-folder "/archive") ;; saved messages
@end lisp
In some case, these static folders may not suffice, and you might want to
change the folders depending on the context; for example, we may have
change the folders depending on the context. For example, we may have
different folders for refiling, based on the sender of the message.
To enable this, instead of setting the standard folders to constant strings,
you can set them to be a @emph{function} that takes a message as parameter,
and returns the desired folder name.
For example, for the refile folder you could put something like the following
in your setup:
@menu
* Smart refiling::
* Other dynamic folders::
@end menu
@node Smart refiling
@section Smart refiling
It is sometimes convenient to move messages to some specific folder, based on
some of the message details -- @emph{refiling}(@key{r}).
We can make this 'smart' with a dynamic refiling folder - each message
automatically figures out the right folder to move to. For example, you could
put something like the following in your setup:
@lisp
(setq mu4e-refile-folder
(lambda (msg)
(cond
;; messages to the mu mailing list go to the /mu folder
((mu4e-message-contact-field-matches msg :to "mu-discuss@@googlegroups.com")
((mu4e-message-contact-field-matches msg :to
"mu-discuss@@googlegroups.com")
"/mu")
;; messages sent directly to me go to /archive
;; also `mu4e-user-mail-address-regexp' can be used
((mu4e-message-contact-field-matches msg :to "me@@example.com")
((mu4e-message-contact-field-matches msg :to
"me@@example.com")

;; message with football or soccer in the subject go to /football

;; messages with football or soccer in the subject go to /football
