qmail is designed with a modular system architecture, so there are a couple of places to add dspam to such a system. VPopmail extends the base qmail delivery process to handle virtual domains and users, which can reside in several different user databases. Whether you want to add dspam at the virtual domain level or user level largely determines the best way to add it to your system.
USER-LEVEL INTEGRATION
If you are only configuring dspam for a small percentage of your users, this is the best method. Configure dspam to use a standalone local delivery agent like safecat (if you already use procmail or maildrop as an LDA, you should call dspam from those tools directly).
First, create a small script called 'maildir_mod' in /usr/local/bin...
#!/bin/sh
VPOPDOMAINS="/home/vpopmail/domains"
if [[ "$2" = "-d" ]]; then
user=`eval echo $3 | cut -f 1 -d "@"`
domain=`eval echo $3 | cut -f 2 -d "@"`
cd $VPOPDOMAINS/"$domain"/"$user"
fi
/usr/local/bin/safecat "$1"/tmp "$1"/new 1>/dev/null
NOTE:
Be sure to configure VPOPDOMAINS to point to the path for your virtual domain directories
Now configure DSPAM:
./configure \ --with-dspam-owner=vpopmail \ --with-dspam-group=vchkpw \ --with-delivery-agent="/usr/local/bin/maildir_mod Maildir -d %u" \ # Your arguments
Next, create a .qmail file in the directory for the user with a line to call dspam, like this:
| /usr/local/bin/dspam --deliver=innocent --user $EXT@$USER
The two environment variables $EXT and $USER are created by the qmail-local program which begins the local delivery process.
DOMAIN-LEVEL INTEGRATION
If you're adding dspam for all users in a domain, you can add dspam directly inline with the vpopmail LDA: vdelivermail. In this mode, you don't need to configure dspam to use a custom LDA, nor do you need to add a .qmail file for all users. Instead, you replace the existing line to the .qmail-default file at the virtual domain level, like this:
| /usr/local/bin/dspam --deliver=innocent --user $EXT@$USER --stdout | /home/vpopmail/bin/vdelivermail bounce-no-mailbox
In essence, you just add the call to dspam (with the appropiate options including --stdout) to the front of the existing line which vadddomain creates when you add a domain.
