Hi,
I contacted the list a couple of weeks ago about SA not missing a lot of
spam I thought it should be catching. There duplicates of message that I
had put through sa-learn, that were still getting passed. One of the
suggestions offered here, after posting my command line here, was that I
should run sa-learn as the user not, as root (silly mistake). That did
improve SA’s ability to catch spam. It cut it down to ~1/2, but I
thought there was more I could do. So, after more digging, I found this
script:
http://wiki.apache.org/spamassassin/IntegratedSpamdInPostfix
I had been using the default Ubuntu configuration, but after
implementing this script, I’ve found SA catching ~90-95% of the spam. So
my faith is now restored
well, a better setup would run spamassassin via milter *before-queue*
and proper reject junk at SMTP level - so you have a tag level let say
between 5.5 and 7.9 points and reject above 8.0
the flagged ones can go in a seperate folder via sieve and the absolute
high score junk is proper rejected and with some luck the spam attempts
go down at all
http://www.postfix.org/MILTER_README.html
If you're already using amavisd with postfix and postscreen, would there
be any benefit to considering a milter in this way?
Spamassassin already verifies authenticity, although not pre-queue, but
I'm not sure that's enough for me to introduce another set of
applications to manage...
Thanks,
Alex
