File Permissions
File permissions can drive you nutz when installing dspam. Here are a few tips.
1. Create a 'dspam' user and 'dspam' group
2. change ownership of all dspam files to be owned by dspam.dspam
chown dspam.dspam dspam_files
3. set the sticky bit (SUID) for the dspam executable (/usr/local/bin/dspam)
chmod 1540 /usr/local/bin/dspam
4. set the correct file permissions of all of the dspam files see: DSpam File Permissions
Configuration
All of DSpam's configuration takes place within dspam.conf (typically located in: /etc/dspam.conf or /etc/dspam/dspam.conf)
Read through dspam.conf, it contains explanations for each configuration option. If you are still unsure after reading dspam.conf, try reading the 'readme' (AKA documentation). If that doesn't help try Google and if that still doesn't shed any light on your problem join the the IRC channel #dspam at irc.freenode.net
