d/l headers for all IMAP folders?

[Kent Watsen]

I set up an IMAP server and use maildrop to do
server-side filtering, which works great except
that Mozilla will not tell me about any new mail
from any folder other then Inbox unless I click
on it - is there a way to get it to download all
IMAP folder headers?  Is this a feature request?

Thanks!
