What kind of security implemention kolab server use?

Helo lists.

   I have a doubt... What kind of security implemention does
kolab 
server 2.0.4 use to drop the spam traffic?

   Example: SPF, greylist, RBLs, Spamassassin and others?

   Thanks

Security and spam are different things.

amavisd-new with spamassassin for spam and clamav for
virus/phishing and such.

RBLs can be enabled easily in postfix or spamassassin
configuration:
http://wiki.kolab.or
g/index.php/Fighting_spam#Using_SBL_and_XBL_lists_from_Spamh
aus_and_ORDB
(though Spamhaus is not free to use for everyone, read their
pages)

The wiki describes the installation of Razor and DCC for
Kolab, too.

Hi Rodrigo

You can do a lot with Kolab2 because it is based on Postfix
it means I have
a kolab2 server which uses following:

DCC (client mode)
RAZOR
Pyzor (do not use both Razor and Pyzor)
Amavisd-new
Spamassassin (internal functions like spf,rbl etc etc) 
F-Prot Antivirus
Sophos Antivirus
Clamav Antivirus
Antivir Antivirus
Additional Rulesets
Manuell HAM/SPAM Definitions

The main config from kolab2 amavisd-new is quit conservativ
it means from my
point of view it can be done more but there is also the
question if this is
really needed on a mailserver it means from my point of view
this has to
taken over by mail gateway and kolab2 does only the last
rudimentary checks
for internal use. If you setup a mailgateway based on
postfix and
amavisd-new there is a similar constellation possible and
lot more! If you
like to extend the config from kolab2 the following link
will help you:

htt
p://www.flakshack.com/anti-spam/wiki/index.php

It depends a little bit which os you use etc. but the config
within amavisd
is for all os the same and you have only to be careful which
file you change
in kolab2 because only *.template file (update with
kolabconf -n) are usable
other changes would be overwritten. Some configs does need
to be changed in
files directly like /kolab/etc/spamassassin/local.cf etc.
I'm fully
satisfied with the solution and I use Solaris Sparc, Intel
Fedora 2 and 3 as
Opteron Sun X2100 Servers which seems to me the best
solution between price,
stability and usage. Have fun...!
