[Dovecot] Getting started with sieve and conversion from procmail

Hi,

My apologies if a previous message appeared twice. Not sure how that
happened...

I thought this was working, but it doesn't create or populate a folder
named xspamstatus although it executes deliver:

procmail: [30333] Wed Nov 16 20:39:36 2011
procmail: Assigning "COMSAT=no"
procmail: Assigning "COMSAT=no"
procmail: Assigning "DELIVER=/usr/libexec/dovecot/deliver"
procmail: Match on "^X-Spam-Status"
procmail: Assigning "LASTFOLDER=/usr/libexec/dovecot/deliver -m xspamstatus"

procmail: Executing "/usr/libexec/dovecot/deliver,-m,mymailbox"
 Subject: Riverside (97293)
  Folder: /usr/libexec/dovecot/deliver -m mymailbox                       28400

I've set lda_mailbox_autocreate to yes, but it still doesn't create
it. Is this folder relative to ~user/mail/ ?

Is there an index file that dovecot-lda updates for imap? Can I just
eliminate it entirely and just have procmail do all the delivery?

Thanks again,
Alex
