Easy way to configure / install Postfix and Spamassassin
Please note: File locations are based on my own install. Yours may be different, and should be checked and appropriate changes made.
1. Install postfix and get it working for your domain. See http://www.postfix.org for
details.
2. Install SpamAssassin. The easiest way to do this is with the command "perl -MCPAN -e 'install Mail::SpamAssassin'" OR you can compile it.
Another way is to use an RPM (RedHat or Fedora) or "apt-get install postfix spamassassin spamc" (if you have debian)
3. As root, create a file at /usr/local/bin/spamfilter.sh with the following content:
#!/bin/bash
/usr/local/bin/spamc | /usr/sbin/sendmail -i "$@"
exit $?
4. Run "chmod 755 /usr/local/bin/spamfilter.sh" then make sure you have it executable: "chmod -x /usr/local/bin/spamfilter.sh"
5. Create a user called 'spamfilter'. Make it a complete user, with home directory and shell. (I prefer setting the shell to false.) example:
useradd -d /home/spamfilter -s /bin/false spamfilter
6. Run "chown spamfilter:spamfilter /usr/local/bin/spamfilter.sh"
7. In /etc/postfix/master.cf in the "Services" section, alter the 'smtp' line as follows (the " -o con..." SHOULD be on the next line: NOTE:
there are two lines that have smtp. Make sure it is the inet line. Usually the first line.
# -----------------------------------------------------------------------------------
smtp inet n - n - - smtpd
-o content_filter=spamfilter:dummy
# -----------------------------------------------------------------------------------
8. In /etc/postfix/master.cf in the "Interfaces to non-Postfix software" section add:
# -----------------------------------------------------------------------------------
spamfilter unix - n n - - pipe
flags=Rq user=spamfilter argv=/usr/local/bin/spamfilter.sh -f ${sender} -- ${recipient}
# -----------------------------------------------------------------------------------
9. Restart postfix and make sure you can still get email. Send a fake spam through the system (from an outside address) to verify that spam is marked
as spam. For information on configuring SpamAssassin, go to http://www.spamassassin.org.

I am getting the same symptoms as described by Lise on 5-12-2007. i.e. no apparent error, messages filtered and "delivered via spamfilter service"
but always delivered to undisclosed-recipients with empty body of the message.
Any follow up on her post ?
Cheers

I would check to make sure all permissions are good. I read in the other post that you had some problems with that. It is a good idea to let the
system create the directories for .spamassassin, etc.
Also ensure your script is passing the proper argument to the spamc.
