Here is my goal:
Internet -> SpamAssassin -> Exchange
I am trying to have spamassassin filter all email traffic and then pass
them, which will include something denoting that it is spam (perhaps put
SPAM in the subject), to the exchange server.
I have done the following and have had no luck:
Running:
Mandrake 9.0
spamassassin 2.44
postfix 1.11.11
procmail 3.22
created /home/user/.forward with the following info (owner "user" permissions 600):
"|IFS=' ' && exec /usr/bin/procmail -f- || exit 75 user"
ACCORDING TO THE SA INSTALL FILE
[EMAIL PROTECTED]
MAIL IS NOT FORWARDED WITHOUT THIS
created /home/user/.procmailrc with the following info (owner "user" permissions 600):
ACCORDING TO THE SA INSTALL FILE
:0fw
| /usr/bin/spamc
edited /etc/postfix/main.cf:
mailbox_command = /some/where/procmail
THIS WAS ORIGINALLY COMMENTED OUT
#mailbox_command = /some/where/procmail -a "$EXTENSION"
THIS WAS NOT CHANGED
#mailbox_command = /usr/bin/procmail -Y -a $DOMAIN
THIS WAS ORIGINALLY UNCOMMENTED
edited /etc/postfix/master.cf:
ACCORDING TO GREG WEBSTER'S HOW TO
added to "service type" section:
smtp inet n - y - - smtpd
-o content_filter=spamfilter
added to "Interfaces to non-Postfix software":
ACCORDING TO GREG WEBSTER'S HOW TO
spamfilter unix - n n - - pipe
flags=Rq user=spamfilter argv=/usr/bin/postfixfilter -f ${sender} -- ${recipient}
created /usr/bin/postfixfilter (owned by spamfilter permissions 755) which contains:
ACCORDING TO GREG WEBSTER'S HOW TO
#!/bin/bash
/usr/bin/spamc | /usr/sbin/sendmail -i "$@"
exit $?
created "spamfilter" user
ACCORDING TO GREG WEBSTER'S HOW TO
created /etc/procmailrc which contains:
I DON'T REMEMBER WHERE I GOT THIS
DROPPRIVS=yes
#Uncomment the following lines to allow for logging
#
#LOGFILE=/var/log/procmail
#VERBOSE=ON
# The condition line ensures that only messages smaller than 250 kB
# (250 * 1024 = 256000 bytes) are processed by SpamAssassin. Most spam
# isn't bigger than a few k and working with big messages can bring
# SpamAssassin to its knees.
:0fw
* < 256000
| /usr/bin/spamc

I am able to type the following command and get results:
spamassassin < sample-spam.txt > output.txt
The results contain a subject of "*****SPAM*****" so this is a desired result.
---------------------------------------------------------------------------------------------
I am able to send email from the SA server to "user" using "metasend -b -s
"TEST" -t user -m plain/text -f /usr/share/doc/spamassassin-2.44/sample-spam.txt".
The email is sent to
the exchange server after about 3 minutes (why so long?). The subject
does not contain "*****SPAM*****" nor are there SPAM header information
therefore I'm afraid I have done something(s) incorrectly. I assume that
the mail is not being evaluated by SA. Please let me know what I'm
missing.
Thanks for your help.
Mark
