These are some steps I took to use dspam with qmail.  If you have a better
method of using qmail with DSPAM, do send a message to me at
<st_lim@gentoo.org> to share your ideas.

My set up includes:
a. qmail
b. qmail-scanner
c. Mail-SpamAssassin
d. f-prot (I'm not using it at the moment, coz mails do get stuck in the queue
when I use f-prot)
e. dspam (of course)

For setting up spamassassin, I think I shall not go into details with it.  I
think an excellent tutorial can be found at
http://cmisip.home.insightbb.com/Qmail.htm.

So once you have spamassassin set up, you will want to use dspam without
procmail.  And since you have .qmail, here is what you do:

1. add your user and qmailq to /etc/mail/dspam/trusted.users
$ cat /etc/mail/dspam/trusted.users
apache
nobody
root
qmailq
alias
st_lim
spteo

2. type the following into your /home/<user>/.qmail file

| /usr/bin/dspam --user <user> --deliver=innocent --mode=teft --feature=chained,noise,whitelist 
[your normal delivery options]

3. When you get spam, you have either of 2 options:
  a. Run the dspam command on the mail via your email client:

==========================================================================================
/usr/bin/dspam --user <user> --mode=teft --class=spam --source=error < [spam-mail]
==========================================================================================

  b. Or run the dspam command on a set of emails in a directory via a cron job,
     my suggested script is below:

==========================================================================================
#!/bin/sh
JUNK_DIR=/home/<user>/Maildir/Junk
JUNK_MAILS=$JUNK_DIR/cur/[0-9]*

QMAIL_SPAMASSASSIN=/var/qmail/.spamassassin

sa-learn --spam $JUNK_MAILS
for i in $JUNK_MAILS; do
  cat $i | /usr/bin/dspam --user qmailq --mode=teft --class=spam --source=error
done
cp $ROOT_SPAMASSASSIN/bayes* $QMAIL_SPAMASSASSIN
chown -R qmailq:qmail $QMAIL_SPAMASSASSIN
rm -rf $JUNK_MAILS
==========================================================================================

If you have any problems with the abovementioned setup, pls share it via
bugs.gentoo.org.  I'll try to help you resolve the issues.
