Hi all. Got put on a project at work to setup some kind of spam

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 ?
www.kana.com
They've moved to a windows only system as of recently. But I plan
to intercept the mail prior to it reaching Kana. I will be having it
forwarded to the filtering server which will then forward all clean
messages to the kana server, bum messages will be dropped in a review box
and later deleted if there is no keepers in there. That will be to be 100%
we're not nabbing legit emails.
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).
hehe. Yeah, that's kinda what I was going to do. :)
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?
Nope, not generated from a web form. They're sent from all sorts
of places. If it were just from a web form, that'd be a lot easier to
handle. But this mailbox receives openly on the net just like any other
mailbox.
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.
Yup, already planned that. :)
