Hi taha_00,
With the new 'image' based spam, I don't know if anything works any more.
I have noticed that a lot of folks are going with 'pre-approved' recipients on their email these days.
You send them a message and it doesn't get delivered until they approve you as a 'sender'.
Once you are approved, the mail flows freely.
The first few times that happened to me it was a pain, but I certainly understand why people have started doing it.

Our offices in the US have this nifty hardware solution.

We are using currently Kaspersky for Exchange version 5.5 no this is not exchange 5.5 ;-) and it lets slip a couple of spam through. the baracuda is better.
Are you guys saying that these solutions are stopping the new "Image Based SPAM" that is primarily coming out of Russia?
The best I have heard about is a 40-50% success rate at blocking that junk.
taha_00,
The SPAM is a lot harder to stop than viruses and malware.
Any number of Anti-virus providers can give you excellent protection again that problem.
On our Domain, we use Symantec products on the Servers and McAfee on the workstations and notebooks.
At home I use McAfee AV 8.0i, MS Defender, Ad-Aware, SpyBot, XP Pro SP2 FW, and a HOSTS file configuration from here:
HOSTS file
http://www.mvps.org/winhel
You can use a HOSTS file to block ads, banners, 3rd party Cookies, 3rd party page counters, web bugs, and even most hijackers. This is accomplished by blocking the connection(s)) that supplies these little gems.
Windows XP = C:\WINDOWS\SYSTEM32\DRIVER
Windows 2K = C:\WINNT\SYSTEM32\DRIVERS\
Win 98/ME = C:\WINDOWS
If you have a specific site or IP address you want to add or block, edit the hosts file as follows:
ADD: 192.168.10.1 companyweb
BLOCK: 127.0.0.1 badwebsite
There are programs that can scan the image and block it based on that, however that is not what I am suggesting.
ORF and GFI both use grey listing, which is a surprisingly good tactic against image based (and other types) of spam.
Also, you will notice that they also include seeming random text at the bottom of those image spam messages - I figured out that it is snippets of text from Stephen King's: Misery - Mr King and the folks at www.stephenking.com (or whatever it is) didn't care...

Just to add my 10 penneth,
We use a McAfee SCM3100 Appliance with the Spamkiller module.
streaming updates every 15 minutes and we get very little in Spam
Just to give you an idea, the readout from the console says
Since 28/9/06 it's stopped 113034 Spam emails, Quarantined 3477 Suspicious Content an 128 Viruses
Stops my graphical ad spam quite nicely thank you very much
Also performs content filtering for the users in the network as well and sits very prettily in my server rack
Cheers

Hi taha_00,
This will depend very much on your organisation, and what you deal with.
Personally, I use GFI (http://www.gfi.com) they are reasonably priced and do a great job.
Our Exchange Page Editor (and Exchange MVP) Sembee also recommends Vamsoft's ORF -> http://www.vamsoft.com/
I have never used this however,
