I'm seeing these entries in my maillog:
May 19 18:16:41 anduril postfix/qmgr[10162]: warning: connect to
transport spamfilter: No such file or directory
May 19 18:16:42 anduril postfix/qmgr[10162]: warning: connect to
transport spamassassin: Connection refused
which leads me to believe Spamassassin isn't working. I'm not sure if
all my mail is coming through so please hit reply all to send to my
yahoo account as well. :-) Thank you in advance for help.
So here's the bullet:
I installed SpamAssassin via cpan and followed the instructions from
"IndegratedDpamdinPostfix" (http://wiki.apache.org/spamassassin/IntegratedSpamdInPostfix
)
I added this:
smtp inet n - n - - smtpd
-o content_filter=spamassassin
and this
spamassassin unix - n n - - pipe
flags=Rq user=nobody argv=/usr/local/bin/spamfilter.sh -oi -f $
{sender} ${recipient}
to my master.cf
I added a user called spamfilter and created this spamfilter.sh
Permissions for spamfilter
[root[at]anduril postfix]# ls -la /usr/local/bin/spamfilter.sh
-rwxr-xr-x 1 spamfilt spamfilt 1036 May 19 09:09 /usr/local/bin/
spamfilter.sh
spamfilter.sh:
#!/bin/sh
# spamfilter.sh
#

# You must first create a user account named "spamfilter" to hold the

umask 077
OUTPUT="`mktemp /tmp/mailfilter.XXXXXXXXXX`"
if [ "$?" != 0 ]; then
/usr/bin/logger -s -p mail.warning -t filter "Unable to create
temporary file."
exit $EX_TEMPFAIL
fi
# Clean up when done or when aborting.
trap "rm -f $OUTPUT" EXIT TERM
$SPAMASSASSIN -x -E -u $USER > $OUTPUT
return="$?"
if [ "$return" = 1 ]; then
$NEW_COMMAND < $OUTPUT
exit $?
elif [ "$return" != 0 ]; then
/usr/bin/logger -s -p mail.warning -t filter "Temporary
SpamAssassin failure (spamc returned $return)"
exit $EX_TEMPFAIL
fi
$SENDMAIL "$@" < $OUTPUT
exit $?
