[Dovecot] maildrop and multi-dbox

Hi there, I'm using Dovecot 2.0.9-1 under Arch Linux.

Currently, I have Maildir configured, and I move all my emails into dovecot by using this sequence:

1. cron starts fetchmail periodically under user manfred to collect my mails from various email accounts.
2. In ~/.fetchmailrc I have configured /usr/bin/maildrop as MDA.
3. In ~/.mailfilter (used by maildrop) I have extensive filtering in place and call bogofilter (by using xfilter) to classify spam mails.

This works fine so far. Now I'd like to migrate to dovecot's new format multi-dbox.

My question now: Is it correct that then I cannot longer use maildrop and would need to switch do dovecot-lda?
