dovecot - Mar 2008 - dspam+sendmail+virtual users

I want to setup something like this...

Sendmail MTA -> DSPAM -> LDA/Dovecot

Can someone give me some sendmail.mc configuration examples on how I
can set this up? I was having trouble getting sendmail to deliver to
dspam and then to dovecot's deliver.

Thanks

PS: I am not using the IMAP DSPAM integratation libs (yet)... I am
using 1.1. When will 1.1 of this come out?
