How to setup SPAM filtering with in Exchange Server 2003
Watch Question


What is Antigen?


Is there is SPAM blocking option within Exchange Server 2003?  
There are MANY different solutions for limiting SPAM.  First you need to decide if you want a hardware or software solution.


Here's some info on the filter built into Exchange. I would suggest looking at a commercial product (like GFI Mail Essentials/Seecurity) to run along side the IMF.




Where do I look in Exchange 2003 server for spam options?
I would look int GFI for both their Mail Essencials product for SPAM and Mail Secuirity for email virus protection.  For the money they are both great products and don't require buying any hardware.  Whatever comes bult into Exchange is NOT enough alone.  You have been warned.  

Read the instructions on the page in the second link I posted. It tells you everything you need to setup and configure IMF. But like mikeleebrla said, IMF in NOT enough to block spam totally. You need to add some commercial software for a true Spam solution.
also don't forget about email virus protection. Virus protection on the server OS itself will NOT prevent email viruses. You need a solution designed to work on Exchange specifically.

I always suggest enabling IMF first. It works for many people. Start with what is free and see whether it is enough for you. I have a number of sites using IMF only and it has been fine.
Personally at home I am only using one other third party tool and that is Vamsoft ORF, which I use for greylisting only. I have not needed to use any other third party tool such as an appliance or GFI.

If you do decide to look at a third party tool then you need to evaluate many different products. Different sites have different spam problems and what works for one, may not work elsewhere. GFI Mail Essentials is very popular with many smaller sites, but I personally haven't had much luck with it.

Microsoft Antigen (formally known as Sybari Antigen) is a top notch AV application, but its antispam capabilities have never impressed me. Most antispam developed by AV vendors are similar in their poor performance.
