==================
Fight against spam
==================

:Description:
    Finally I managed to bring my server up to dat regarding spam and
    antivirus facilities. 

Finally I managed to bring my server up to dat regarding spam and antivirus
facilities. 

Most I did was to reconfigure `amavisd-new`__ (which I'm using with
`Postfix`__), replace the outdated `OpenAntivirus`__ with `ClamAV`__ and
install the newest version of `Spamassassin`__. Beside that I installed
`Razor2`__ and integrated it into Spamassassin. As Spamassassin weights Razor2
hits usually only with abou 1 point, I raised that setting to 2.5. Today every
of the (non-mailinglist) spam I got was filtered perfectly and I got no false
positives.

I hope that lasts for the upcoming times to avoid most of the fu\*\*ing spam.
The new virus scanner is updated frequently, so my Windoze using friends using
that mail server are secured from ugly virii.

I plan to migrate my Postfix and Spamassassin settings to MySQL in future. So
specialized settings for both can be stored individually for each mailaccount.
Especially black and white lists. `SquirrelMail`__ (my webmail system) should
support that quite nicely.

The only spam issue I did not fix yet is spam along mailinglists. The PEAR
webmaster and CVS lists produce spam every day. Through the list system, most
headers get fixed and through auto-white-listing of Spamassassin those mails
get a positive addition in scoring. If anyone has an (implementable and
usable) solution on that, feel free to comment!
