Tony, is it possible to get from you the rpms for centos 4.x also how you
implemented the dspam solution
[...]
I have antiquated dspam rpms for RHEL4, better to get the RHEL5/FC6 srpm
and rebuild on your platform - I'm not sure about the MySQL version on
RHEL4, though - but it should work. This is all Postfix stuff, by the
way. My present PF version is 2.5.0.
They're at ftp://ipd50aa34e.speed.planet.nl/, which is my home FC6 machine.
The set up is that dspam runs as daemon content filter between the last
two of three smtpd listeners and PF then hands the mail to the Courier
maildrop LDA which delivers to IMAP mail directories:
[...]
:10025 inet n - n - 100
smtpd
-o content_filter=lmtp:[127.0.0.1]:24
-o lmtp_send_xforward_command=yes
-o lmtp_destination_concurrency_limit=5
-o smtpd_client_restrictions=
-o smtpd_helo_restrictions=
-o smtpd_sender_restrictions=
-o smtpd_error_sleep_time=0
-o smtpd_recipient_restrictions=permit_mynetworks,reject
-o
receive_override_options=no_unknown_recipient_checks,no_header_body_checks
-o disable_mime_output_conversion=yes
:10026 inet n - n - 100
smtpd
-o content_filter=
-o smtpd_client_restrictions=
-o smtpd_helo_restrictions=
-o smtpd_sender_restrictions=
-o smtpd_error_sleep_time=0
-o smtpd_recipient_restrictions=permit_mynetworks,reject
-o receive_override_options=no_unknown_recipient_checks
-o smtpd_milters=inet:localhost:10004
-o milter_default_action=accept
-o milter_macro_daemon_name=ORIGINATING
-o disable_mime_output_conversion=yes
[...]
The milter is dkim-milter 2.4.3
[...]
maildrop unix - n n - - pipe
flags=Rhu user=vmail
argv=/usr/bin/maildrop -w 80 -d ${user} ${sender} ${recipient}
${extension}
[...]
As stated there is no GUI. maildrop filters to each user's IMAP dspam
quarantine directory with a [dspam] header and the user moves to a dspam
misjudged directory for retraining if dspam has made a judgment mistake.
A cron job runs every so often to look for misjudged mail and there are
cron-based routines to look for unread quarantine messages and chide
users, etc.
dspam on all rigs runs MySQL 5.0 and uses a shared group. dspam.conf:

Steve has a number of problems with the above dspam.conf, but it runs
fine in more or less the same configuration on my rigs.
Thanks!
