using format-time-string in nnimap-split-methods

[David Bonnafous]

Hi,

I keep the email I send in folder named "mail/inbox-year-month" with
this configuration:

(setq gnus-message-archive-group
      '((concat "mail/inbox-" (format-time-string "%Y-%m"))))

It's working.

But, I try to split my INBOX with a similar configutation:

(setq nnimap-split-methods
      '(((concat "mail\/inbox-" (format-time-string "%Y-%m")) "")))

but it doesn't work (nothing is splited).

So I use 

(setq nnimap-split-methods
      '(("mail\/inbox-2013-12" "")))

it's ok but it's bad, isn't it :(

Could you help me ?
