Resolved Problem with Spam

Erick Nunes

Basic Pleskian
Hello friends. I am having a problem with too much spam received on my server.
My SpamAssassim is score 8.

What can I do to get fewer spam? Does it make sense for me to stop using SapmAssassim and buy MagicSpam?

Thank you
 
Some very general points on fighting spam, if they are usefull is for you to decide:

- lower the number, personally i use 5 and for client servers we set 7
- mark spam, don't delete it, if you have a false positive due to the low number, it will not be lost
- don't use the blacklist, you can't place the world on it
- use the whitelist, if a senders triggers a false possitive, whitelist it.
- use a spamfilter in your mailclient (thunderbird as a build in one)
- don't delete spam when it arrives in your mailclient, use the "spam, "junk", "what-ever-it-is-called" button to train your spamfilter
- don't use a catch-all
- don't use a out-of-office repley, its telling the spammers: yes this email exists, you can place it on your spamlist

- update spam on a regular basis. We use this script to do this

WARNING: this is a centos script. If you use ubuntu or another unix flavor you must check if the paths are correct.

Code:
#!/bin/sh

# update spamassassin
sa-update -D --updatedir /usr/share/spamassassin

# delete old rules and copy new rules to rule dir
rm -f /usr/share/spamassassin/*.*
cp /usr/share/spamassassin/updates_spamassassin_org/*.* /usr/share/spamassassin/

# restart
service spamassassin restart

just my 2 cents

regards
Jan
