^C TAB can't see mail from spamassassin

[Kenton Brede <kbrede@xxxxxxxxxxxx>]

I've just set up spamassassin.  I'm sorting through procmail.
Everything works fine in terms of sorting and spam collecting.  I'm
having spam messages sent to the courier-imap folder INBOX.spam.  I
can see the mail fine when I look in that directory but mutt doesn't
seem to know they have been sorted there.  When I hit "^c TAB" the
directory doesn't automatically come up so I can just hit return.  
How can I get mutt to "see" these mails?  All other sorted mail mutt
knows is there. 

~/.procmailrc

:0fw
| spamassassin -P

# used to add length to messages
:0 Bfh
* H ?? !^Lines:
* -1^0
*  1^1 ^.*$
| formail -A "Lines: $="

:0:
* ^X-Spam-Status: Yes
$MAILLISTFOLDER.spam/new

Thanks for any help.  I searched google and the list archives and
couldn't find and answer to my problem.
