dovecot - Feb 2009 - delivering to folder based on recipient_delimiter?

I'm currently running postfix + dovecot, with virtual users

In postfix I have set recipient_delimiter = + so that postfix accepts 
mail for user at example.com, user+foo at example.com, and 
user+spam at example.com all deliver to inbox.

what I would like is to have email directed to user+foo at example.com 
delivered to the IMAP folder foo  (and, in the context of amavisd, 
have amavis configured for recipient_delimited, and add 
addr_extension_spam_maps add +spam to each mail identified as spam, 
and thus the mail would go to the spam folder on delivery.

The postfix guys say I should be able to do this. can someone point 
me to how to implement this with dovecot? (as I don't see how to even
start).

Thx

Rick

I use Sieve to do this. There's probably other ways, too.
