Dedicated Spam box filter

Hi there,

I've put amavisd and spamassassin onto a scalix server before and done so successfully. Some times there have been bugs (with either scalix or amavisd) and I have decided to keep things simple and modular. I would like to point all incoming email to a machine dedicated to filtering spam and viruses which, in turn would pass it to the dedicated scalix machine. That way, if we ever need to upgrade or configure scalix the other machine will also be acting as a mail queue while the scalix machine is offline.

INTERNET--->router--->Spam Filter--->Scalix is the general idea.

I'm sure someone has done this before but I'm just not sure of the terminology I should be searching for...I keep coming across commercial products and things where I'm completely satisfied with the protection that amavisd provides and would just like to put this on another machine. Any detected spam would get labelled and individual or global scalix filters could then sort them out.

Can anyone point me in some direction to get started? I'm sure it'll be a barebones install of sendmail, amavisd and not much else.

Kindest regards,

kkjensen

I have this configuration running for several years now, works great. I have a simple debian machine in front of Scalix, running Postfix/Amavisd-new. I also have this machine reject mails from unknown mail-adresses.

If you Google for something like "Postfix mail gateway", you can find several howto's on this.

'gateway' was the word I was missing! Perfect! Thanks a lot. I found a few howtos.

take a look at esva . vmware based anti-spam appliance

we're using this one here in front of our scalix services, so we keep scalix entirely behind our firewall.

prebuilt...I like that. Especially if we can just restore a snapshot if something gets messed up. Cool. Thanks for the heads up.
