Outlook, IMF and SPAM

[Jonboy]

We're running SBS 2003 with Outlook Exchange 2003 and clients on Outlook 2003 and 2007.

We've been getting an increasing load of spam lately, from lotto winnings to Viagra adds and Rolex watches. Not to mention a whole host of "Online banking account suspended" phishing mails.

I used to think our NOD32 filtered our spam until I delved deeper and discovered it's purely antivirus.

So I went in and had a look, our IMF was set to filter out messages with an SCL of 9 and above (which is actually no filtering due to the bug which actually means anything from 10 gets blocked). I've now dropped this once to 8 and again to 7 but we're still getting spammed left right and center. I don't want to drop our IMF too much because then we'll start getting false positives. What solutions are you guys running for spam filtering?

We have the same setup as you, With nod32 too..

On the NOD32 excahnge scanner, there is a spam filtering system, but most of the time you need to add the filtering rules.

If you are willing to invest in a computer, why dont you set up a dedicated linux spam filter ?

In my opinion these applications that attached it self to exchange is looking for trouble.
Cus they tend to stick their fingers deep into exchange's core. and it creates more failure points.

Setting up a linux mail relay with spam filtering is pretty easy with mailsend or posfix.

We have also had a spam filter before our company got centralized from a company that "claims' their spam engine is used by google's Gmail.
Which is Sophos based.
Dont know how true that is but that spam filter was pretty good and i miss it, if was up to me i would buy their services again.
Also dont worry We get loads and loads of spam especially Nigerian and phishing scams.
