As demon says, SDPS works by accessing "the same mail spools as are used 
by SMTP". Dovecot does not do this. And I don't see a need for that. 
Configure your MTA to put the envelope data into the mail header (e.g. 
Return-path and Envelope-to). I used this several times for 
multidrop-mailboxes (which also seems to be the main use of SDPS).
