Spam assassin and postfix..
Hello,
I configured sapmassassin with postfix.
Sapmassassin version is spamassassin-3.0.3-4.fc4
Here is my spam filter script..
******************************************************
*[root@localmail log]# cat /usr/local/bin/spamfilter
#variables
SENDMAIL="/usr/sbin/sendmail.postfix -i"
EGREP=/bin/egrep
# Exit codes from <sysexits.h>
EX_UNAVAILABLE=69
# Number of *'s in X-Spam-level header needed to sideline message:
# (Eg. Score of 5.5 = "*****" )
SPAMLIMIT=5
# Clean up when done or when aborting.
trap "rm -f /var/tempfs/out.$$" 0 1 2 3 15
# Pipe message to spamc
cat | /usr/bin/spamc -u spamfilter > /var/tempfs/out.$$
if $EGREP -q "^X-Spam-Level: \*{$SPAMLIMIT,}" < /var/tempfs/out.$$
then
## Change the Email address where you want your spam to get fwd to
$SENDMAIL -f jaitest@aleks.com < /var/tempfs/out.$$
else
###$SENDMAIL "$@" < /var/tempfs/out.$$
$SENDMAIL $@ < /var/tempfs/out.$$
fi
# Postfix returns the exit status of the Postfix sendmail command.
exit $? *
******************************
I made these changes in master.cf file..
Changed this line by adding "-o content_filter=spamfilter:dummy" to the
default
*smtp inet n - n - - smtpd -o
content_filter=spamfilter:dummy *
Added next two lines..
*spamfilter unix - n n - - pipe
flags=Rq user=spamfilter argv=/usr/local/bin/spamfilter -f ${sender}
-- ${recipient} *
Once postfix reloaded I can see that mails are being processed by
spamfilter.
But for some mails I get these kind of error in the log file and user
receives mail from MAILER-DAEMON
Can some please tell me why we get these only for some mail and how to
get rid of this problem.

The clue is in the error log. It says you must use "-t" or specify the
recipient on the sendmail command line. In the case the message is
detected as spam, you do this:
$SENDMAIL -f jaitest@aleks.com < /var/tempfs/out.$$
There's no -t and no recipient. The -f option is the "from" part. I
suspect you want to send spam to jaitest@aleks.com, in which case
try something like this:
$SENDMAIL -f $2 jaitest@aleks.com < /var/tempfs/out.$$
$2 should be the sender, as passed into the filter script.
Rather than calling spamc on each message, you might also consider
a daemon solution which will reduce the overhead and startup delay
time. Very helpful if processing a lot of mail. I use amavisd-new
and have it run clamd before spamassassin. There are others that
have been mentioned in this mailing list, as well.
