[mew-int 3013] how to delete email into gmail trash folder ?

[ZhangJun]

I have config in .mew.el like this:

(setq mew-config-alist
      '(
        ("default"
	 (...)
	 ("imap-trash-folder" . "%Trash")
	 (...)
	 )
	 )
)
      

I want to the deleted emails go to gmail's "Trash" forlder (in web page),
but this configure seems put delete emails into a lable "[Imap]/Trash",
there are also "[Imap]Drafts" and "[Imap]/Sent" Labels,

in gmail webpage there are "Inbox", "Sent Mail", "Drafts" and "Trash",
I want to use these forlders.

thanks!
