What should be done

  • It should create 2 addresses, spam@daomin.tld and nonspam@domain.tld
  • It should set OptOut to on and OptIn to off for those 2 addresses
  • Probably create the and for every new added domain. But, if we use pcre maps, this should only be done if both maps are non existant.

Actually, there's no need to do any ISPMan modifications, you only need to setup your dspam, and change parts of postfix(minor things).


Installing DSPAM

I install DSPAM trough an ebuild that I created myself for Gentoo, but the configure options it uses are:

./configure --prefix=/usr \
--host=i386-pc-linux-gnu \
--mandir=/usr/share/man \
--infodir=/usr/share/info \
--datadir=/usr/share \
--sysconfdir=/etc \
--localstatedir=/var/lib \
--with-logdir=/var/log/dspam \
--with-dspam-mode=02510 \
--with-dspam-owner=dspam \
--with-dspam-group=dspam \
--enable-long-username \
--enable-large-scale \
--with-dspam-home=/var/spool/dspam \
--with-dspam-home-mode=770 \
--with-dspam-home-owner=dspam \
--with-dspam-home-group=dspam \
--sysconfdir=/etc/mail/dspam \
--enable-clamav \
--enable-ldap \
--enable-debug \
--enable-verbose-debug \
--enable-bnr-debug \
--enable-daemon \
--with-storage-driver=mysql_drv \
--with-mysql-includes=/usr/include/mysql \
--with-mysql-libraries=/usr/lib/mysql \
--enable-preferences-extension \
--enable-virtual-users \

For the DSPAM's web UI part to work, all files can be owned by the user running your webserver but it IS required that the user belongs to the dspam group. Optionally if using apache you can use SuExec to run the web UI with user/group dspam:dspam.

My Gentoo ebuild also creates some dirs, which I dont know if DSPAM creates if not found and those are:

mode owner group file/dir
770 dspam dspam /var/spool/dspam
770 dspam dspam /var/spool/dspam/opt-in
770 dspam dspam /var/spool/dspam/opt-out
770 dspam dspam /var/spool/dspam/txt
770 dspam dspam /etc/mail/dspam
775 dspam dspam /var/run/dspam
770 dspam dspam /var/log/dspam

You can/should also:

txt/* /var/spool/dspam/txt

The web UI files can be installed in diferent ways. You can copy everying to for example /var/www/localhost/htdocs or split cgi files and normal web files between the cgi-bin dir and the htdocs dir, it's all up to you.

Some usefull files are:

File: /etc/logrotate.d/dspam
/var/log/dspam/sql.errors /var/log/dspam/system.log /var/log/dspam/dspam.debug /var/log/dspam/dspam.messages {

File: /etc/postfix/
/^spam@(.*)$/                        dspam:spam
/^(nonspam|notspam|innocent)@(.*)$/  dspam:innocent

This transport map allows users to submit spam to spam@domain.tld, and non spam to nonspam@domain.tld, notspam@domain.tld and innocent@domain.tld. Note: To submit spam/nonspam the emails MUST be forwarded.

In postfix's you MUST also change $transport_maps to add this new transport map file, like for example:

File: /etc/postfix/
transport_maps = pcre:/etc/postfix/ ldap:/etc/postfix/

The user used to call the dspam binary, must exist on the dspam database, you could probably use the spam or the nonspam user.
