Hi all. Got put on a project at work to setup some kind of spam
and junk mail filtering for our Kana mail system, which if you know what
Kana is it's used for our helpdesk people to track problems within the company.
Never heard of it. I presume it runs on *nix ?
If it doesn't, one possibility is to set up a mail gateway host - a
separate machine which accepts the mail and relays it to the Kana box. Of
course, the typical "gateway" configuration is an SMTP-only thing, and
here, what you'd want to do is run the messages through procmail on the
gateway host (assuming a gateway is necessary), and have procmail forward
them. Your kana box could be (hopefully) configured to accept mail ONLY
from the gateway host (at a minimum, you could firewall it at the boundary
of your LAN).
Anywho, we're receiving an inexhorbinant amount of spam and unwanted
garbage like viruses and bounce messages into the box while only seeing
maybe 2-3 legit emails a day in there.
Any chance that the legit emails have a certain _format_ to them? Are they
say, generated from a web form?
server that works like a charm and has never failed me once. However, I'm
not sure if that recipe will work for a Kana mail style system so that we
don't accidently filter out valid emails.
When setting up filters, it is always a good idea to spend a certain amount
of time reviewing logs - seeing what the filter is discarding. Except, you
don't merely throw the messages out - you archive them to a mailbox from
which you can recover them if necessary.
I'm also going to be implementing Spam Assassin with this as well, but
I've got that part covered already in another mailing list. I'm just
more or less wondering if anyone here has successfully used Procmail to
filter a Kana system before and what you might have used as a recipe.
Nope, never so much as heard of Kana.
