Well, it seems nobody "official" is stepping in here, so I will have a 
go :-)

Obvously all readmes and docs need to be applied with some thought, 
never just slavishly cut and paste. What you need to think about is:
- How is mail handled by YOUR postfix ? Draw maps of how a mail flows 
(incoming and outgoing) in YOUR specific system.
- Think about which mails you want piped through dspam (usually not mail 
from you to the world).
- If you have special needs, you may ned to either
        x) set up a recipient map or transport map on your smtps port to 
handle <user>-spam and <user>-nospam.
            I find that a bit fiddly,
        x) set up multiple postfix instances to easily route mail from 
different sources through dspam once and only once.
            Debian has a nice framework for doing so.
        x) remove the filter and set up dspam as local delivery agent, 
which in turn delivers to the mailboxes.
        x) other alternatives I can not remember right now

NOTE! You most likely do NOT want to set up dspam accounts for everyone 
you ar sending mail TO. For my own server, most of the mail I get 
through smtps MAY be ment for <user>-spam@myhost or 
<user>-nospam@myhost, but other than that I do not want mail submitted 
through smtps to go via dspam. In fact I found using the retrainging 
through mail-adresses to be cumbersome, so I have set up my local 
mail-store (dovecot) to retrain whenever users move mail into/out-of the 
spam folder by using the dovecot antispam plugin. Far cleaner.
