 |
|
I need to setup my server to be an accurate anti-spam machine! I have the basic SpamAssassin up and running but I know it can be extended. I have read tons on the forums about different configurations but I am lost. Could someone help point me in the right direction.
mail-mta/postfix-2.1.5-r2
mail-filter/procmail-3.22-r6
mail-filter/spamassassin-3.0.4
/etc/postfix/main.cf
| Code: | ...
mailbox_command = /usr/bin/procmail
... |
/etc/procmailrc
| Code: | MAILDIR=$HOME/.maildir
SPAMDIR=$MAILDIR/.Spam
:0fw
* < 256000
| /usr/bin/spamc -f
:0:
* ^X-Spam-Status: Yes
$SPAMDIR |
/etc/mail/spamassassin/local.cf
| Code: | required_hits 5.0
report_safe 1 |
Would a [hourly] cron job as follows work to help SA auto-learn spam and ham
/etc/cron.hourly/sa-learn.cron
| Code: | #!/bin/sh
HOME_DIRS="/home/"
MAIL_DIR="/.maildir"
HAM_DIR="$MAIL_DIR/cur"
SPAM_DIR="$MAIL_DIR/.Spam/cur"
for USER in `ls $HOME_DIRS`; do
sa-learn --ham -f $HOME_DIRS$USER$HAM_DIR
sa-learn --spam -f $HOME_DIRS$USER$SPAM_DIR
done |
Anyone who can give me recommendations on how to better improve my anti-spam measures would be greatly appreciated! |

This would work, but might give odd results...
Since you're just telling SpamAssassin to learn what he alread knew. The thing I do (I can post the script, if you're interested) is to have SA wait for me to confirm that spam is spam and ham is ham before learning it.
Basicaly I have it check (every night) if there are any "read" messages in the spam-dir. all those are confirmed spam. All "read" messages in the inbox are confirmd ham. That way he will learn from his mistakes.
Every day (er every week, depending on how busy I am) I check the spam-dir and use the "mark folder as read" if it's ok. |

But what about the fact this would use the 'cur' dir and not the 'new' dir? If I am off base, I would greatly appreciate you posting your script. Just curious, but do you use any of the network measures? [pyrzor/razor/dcc]

Cur just means that the email-client has already seen it; but not that the USER has seen it.
I haven't got time to fine-tune my SA-setup... also I didn't need to fine-tune it, since it works as it should right now...
here's my script (run nightly) | Code: |
# Learn all messages that are seen and NOT flagged
echo -n "Learning ham: "
mails="$(find ~/.maildir/cur/ -daystart -type f -and \
-name '*S' -and ! -name "*\:2\,*F*")"
if [ ! -z "$mails" ]; then
sa-learn --ham --no-sync --showdots $mails
mv $mails ~/.maildir/.old/cur/
echo "done"
else
echo "none"
fi
# remove all confirmed (seen) spam
echo -n "Learning spam: "
mails="$(find ~/.maildir/.spam/cur/ -name '*S' -and ! -name "*\:2\,*F*")"
if [ ! -z "$mails" ]; then
sa-learn --spam --no-sync --showdots $mails
rm -f $mails
echo "done"
else
echo "none"
fi
# rebuild spam-db
echo "Rebuilding spam db..."
sa-learn --sync --showdots
