I re-read the original... are you sure you are using Dovecot deliver? I didn't 
think it created mailboxes for non-existent users? I mean is "<user>+spam" a 
user? If not then why is a directory being created? Just seems weird but 
maybe deliver does that.

My only thought is make sure these lines (or something appropriate for your 
setup) is in Postfix's main.cf.

recipient_delimiter = +
dovecot_destination_recipient_limit = 1
virtual_mailbox_domains = your.domain.here
virtual_transport = dovecot
